In the SSSR, the realization of this approach dates from 1928. Major efforts are,12'6wever, of more recent origin (1959). The dynamic transformations of the south tayga forest vegeta- tion are most,frequently related to antropogenic cauSeS, - forest fires, forest ex- ploitation, convefsionto-farmland and farming abandonment. In arid and mountainous regions, major veget 'ation changes are known to be fastj In the plains of tile southern tayga, except in the marches, these clianges are quite slow and thus cannot be reflec- ted in maps.

The modulator is made up of an optical head and an electronic unit. The optical head consists of a rotating prism with total internal reflection that acts as one of the mirrors of the laser optical resonator; it is,driven at angular speeds up to 26 x 103 rpm by a dc motor'. The electronic unit consists of a square wave generator, a comparator circuit, two time delay networks, a trigger cir- cuit, a dc motor, and a power supply. The modulator operates in the following mannert at a given angular position of the prism with respect to the laser beam, light from a lamp is focused through a lens and illuminates a photosensitive diode. The output pulse of the photodiode is amplified and fed to the comparator. When the rotational speeds of the motor and the prism are equal, the comparator initiates a pulse that lightsthe laser pumping lamp and thus triggers the laser. At the same time, the 43041-66 Z NRt AP6029519 motor is stopped and the laser is not triggered again until the motor build$ up its speed until it is equal to that of the prism. The motor has an automatic disconnect relay which stops it in 5 to 7 seconds if a faulty condition occurs in the circuit. As a result of work with the modulator, optimum parameters for the optical resonator, rotation speed of the itflector, and pumping power have been determined in order to ,IV) obtain maximum output pulse power.

To this end, the product of.the tangents of the angles of inclination.in the amplification character- istics must remain constant over the whole.mange-of signal changes.

The EA is connected according to the diagram of a parallel equilibrium of 6P3 tubes and - ex- cept for the,6Kh6 tubes - does not differ from ordinary d.c. amplifiers with a constant amplification coefficient. To obtain the nonlinearity demanded In the circuit diagram, a 6Kh6 twin diode is used. A positive retardation potential is brought near its cathode. The value of this potential can be regulated by a potentiometer. As long as the voltage of.the input signal is smaller than the retardation voltage, the 6Kh6 tube does not affect the work.of-the wiring, ''and the. amplifier yields the maximum amplification.

By changing r and r-,any gradient of the characteristic 4 towards the point of inflection can be obtained. The.charac- teristic of the EA without the 6Kh6 tube is an envelopeL of the whole family of characteristics. The point of inflection can be obtained in any spot of this envelope. The total.gradient of the characteristic before and after the point of infleation is determined in dependence on the necessary amplification coefficient by means of the resistor r and the current reverser P2 which shunt the input of the amplifier. The amplifier is very convenient for work in the laboratory as it can produce practically any characteristic.

The time constants of the circuit-diagram elements greatly influence the compensating resistance. The author demonstrates that the compensating resistance greatly depends on the frequency at large values of the time constants. The value of the compensating resistance is easily obtained from the amplitude-versus-.phase characteristics of the open system. It is recommended to choose the compensating resistance according to the stability conditions of the system; In rapid-speed "recesses, the corre3poliding point on the amplitude-versus-phase characteristics is found 11car the origin of coordinates. This is why the equivalent circuit resistance is here almost equal to the natural one (without Card 1/2 compensation).

Ferromagnetism PERIODICAL: Fizika metallov i metallovedeniye, 1959, vol 8, Nr 3, PP 330-336 (USSR) ABSTRACT: Usually the ferro and antiferromagnetism of transition metals is explained by the exchange interaction between the electrons of inner d-shells. If the exchange interaction integral between nearest neighbours is positive, then the metal is a ferromagnetic, while if it is negative the metal is antiferromagnetic. Such a treatment of magnetic properties meets with a number of difficulties. A large group of experimental data cannot be explained ifith the aid of the Bethe-Slater curve for tho exchange integral of transition metals (Ref 1). Moreover, the majority of theoretl*cal estimates of the exchange integral gives it a negative sign (Ref 2). Secondly, it has recently been found (Ref 3) that diluted alloys of manganese with noble metals are either Card 1/5 ferro or antiferromagnetics. In these alloys the atoms 66219 SOV/126-6-3-2/33 On the Role of Indirect Interaction in the Theory of the Magnetism of Transition Metals and Rare Earths. 1. Ferromagnetism of the transition metal are at such large distances from each other that direct exchange coupling between them is entirely excluded. Similarly, ferro and antiferro- magnetism of rare earth metals cannot be explained by unusually weak direct coupling between magnetically active electrons. These considerations have led to a search for other possible mechanism of exchange coupling. One of such mechanisms is the indirect exchange interaction suggested by Zener (Ref 1). The present work is concerned with the effect of indirect interaction in the ferromagnetic problem. The theory is based on the s-d-exchange model of transition metals put forward by Vonsovskiy, his coworkers., and Berdyshev (Refs 4, 5). The Hamiltonian which describes the interaction between conduction electrons and spin waves in a fez-romagnetic is given by Eqs (1) and (2) (Ref 4).

In previous papers on the s-d-exchange model (Refs 4 and 5) only the H 0 and H2 components were taken into account which corresponds to taking into account in the energy first order corrections of the perturbation theory. The contribution due to the "triple" terms in the energy spectrum was not considered and it is the aim of the present work to elucidate the effect of these terms on the energy of the system and its magnetization. It is shown that the second approximation of the perturbation theory on the s-d-exchange model of transition metals leads to the appearance of an indirect interaction between d-electrons. When this interaction is taken into account the existence of ferromagnetism becomes possible in the / 66219 SOV/126-8-3-2/33 On the Role of Indirect Interaction in the Theory of the Magnetism of Transition Metals and Rare Earths. 1. Ferromagnetism case of complete absence of direct coupling or even negative d-d-exchange integral. An expression is derived for the d-d-exchange integral and this is given by Eq (11). Froin this expression it can be seen that in the present theory the energy of the spin wave is considerably altered in comparison with the exchange model. Firstly, the second order correction of the energy has led to the replacement of the integral of direct d-d-exchange coupling by a certain effective integral whose magnitude depends on the Fermi energy and the transport integral for conduction electrons. Secondly, the effective exchange integral is not very dependent on temperature. Finally, the second order correction of the energy completely cancels the effect of the first order correction so that the "zero" energy 1k, which was considered earlier in Refs 4 and 5, is completely absent in the spin wave energy, This means that the spontaneous magnetization of d-electrons follows the T3/2 law in contradiction to the Card 4/5 results obtained in Refs 4 and 5 and this is entire ~ldue 66219 SOV/126-8-3-2/33 On the Role of Indirect Interaction in the Theory of the Magnetism of Transition Metals and Rare Earths. 1.

Thus, firstly, the large group of experimental data cannot be explained by t-he Bethe-Slater (Bete, Sleyter) curve for the exchange interaction integral of transition metalso Secondly, the majority of theoretical estimates of this integral leads to a'negative sign (antiferromagnetic)(Ref 2)~ and, thirdly, diluted alloys of manganese with noble metal's show ferro- or antiferromagnetism (Ref 3)- In view of the fact that by means of this theory it is apparently not possible' to describe these phenomena Card 1/3 correctly, it is necessary to search for another form of On the Indirect Interaction of d-Electronn I -A of Transition Metals representing the exchan-e inter:iction; 'the present paper makes acontribution in this (Ii-ection.

The s-d model of the transition metals is treated on the basis of the perturbation theory in second approxim-ation; this leads to indirect inter- action between the d-olectrons in which the conductivity electrons are involved.

It was shown that the indirect interaction between electrons in inner and incompletely filled shells, in the atoms of transition metals and rare earths, favours the formation of a ferromagnetic state. In the present paper an estimate is made of the role of indirect interaction in setting up antiferro- magnetic order.

The spin operators can be related to the Bose operators by the two equations at the bottom of p 481 and top of p 482. The Hamiltonian obtained in this way is shown at the top of p 482 where z is the number of nearest neighbors for a given atom, Yx and 0 is the radius vector from the atom to its nearest neighbor atom. After diagonalization, the Hamiltonian can be thrown into the form shown at the Card 2/4 bottom of p 482 where e% and g(%) are defined by the 8021-1 S/126/60/009/04/001/033 E032/E435 The Role of Indirect Exchange Interaction in the Theory of the Magnetism of Transition Metals and Rare Earths II. Antiferromagnetism relations at the bottom of p 482. The energy of the system in an external magnetic field, the free energy and the magnetization are then calculated in a way similar to that employed in the previous paper (Ref 1). It is shown that if the interaction of spin waves with conduction electrons is taken into account, then the interaction between d-electrons is characterized not by the d-d exchange integral but by a certain effective exchange integral Jeff which is given by Eq (6), in which 15 is the chemical potential of the conduction electrons. It follows from this equation that in the absence of direct d-d exchange interaction, the integral Jeff is negative, which means that the energy of the spin wave also becomes negative and an antiferromagnetic state cannot be reached. It is concluded that indirect exchange interaction in general favours ferromagnetism and tnis agrees with Zener's hypothesis. The electronic specific heat of transition metals is also affected by indirect interaction.

In the antiferromagnet:Lc metal Interactlomof conductivity electrons with spin waves occur which are specific for such metals. In this brief note, the author investigated mathematically the problem of the influence of this inter- action on the occurrence of a superconducting state. It is shown that electron-magnon interaction leads to effective interaction of electrons with pulses of opposite polarity and spins and this interaction is repulsive ir. character in contrast to the electron-phonon interaction. The bond energy of the Cooper electron pair, forming as a result of electron-uhonon interaction, can only decrease and the Cardl/2 pair can generally be annihilated as a result of scattering L411" 80530 S/126/6o/009/05/022/025 EOJa~E~~ On the Problem of the Existence of a e 9nducting State in Antiferromagnetic Metals of electrons on the spin waves. The repulsive character of the electron-electron interaction, due to exchange with spin waves, is explained by the fact that the scattering of electrons is accompanibd by spin Clip. If one of the electrons of a Cooper pair is scattered on a Spin wave, it changes the direction of its spin; electrons with parallel spins cannot form a conjugate pair.

TITLE, On the Existence of Supdrconducting Antiferromagnetics PERIODICAL.~ Fizika metallov i metallovedeniye., 1960, Vol.10, No.2, PP-301--302 TEXT. The superconductivity criterion for antiferromagnetic materials was discussed by the present author in Refs.1 and 2. In Ref,2 use was made of a reduced electron-electron Hamiltonian des---ribing the interaction between electrons with opposite momenta and spins due to spin-wave exchange effects in antiferromagnetics. The positive sign of the effective interaction potential showed that electrons forming a Cooper pair repel each other as a result of scattering on magnons, In the present note the author discusses the effect of inelastic scattering of electrons by magnons on the appearance of superconductivity, using the method proposed by Bogolyubov in Ref,,3, The flamiltonivn for the electron-phonon- spin-wave system consists of three parts (P~301) and includes the s - d exchange integral I , the electron-phonon coupling constant 9 the chemical potential of conduction electrons and the number of nearest neighbours z .

Following the discovery of superconducting ferromagnetics by Matthias et al (Ref,l), the problem of the connection between superconductivity and ferromagnetism has acquired a considerable interest, Vonsovskiy and Svirski- (Ref.2) have shown that the magnetization of the conduction electrons by the exchange "field" prevents the formation of a superconducting state. However, no one has so far investigated the effect of inelastic scattering of conduction electrons by spin waves of the superconductivity of a ferromagnetic, The present author investigates this problem using the Hamiltonian of the s -d exchange model put forward by Vonsovskiy and Turov in Ref.3. The Hamiltonian is simplified by neglecting terms responsible for the magnetization and retaining terms responsible for inelastic scattering. This simplification is Card 1/2 6" 'T1 5M S/126/60/010/005/028/030 E032/E414 The Effect of Scattering of Conduction Electrons by Spin Waves in a Ferromagnetic on the Temperature of Transition in the Superconducting State said to be justified by the fact that the role of the neglected terms has already been investigated by Vonsovskiy and Svirskiy (Ref.2) and the analysis would only be complicated by them without altering-the overall qualitative pi--ture, The results obtained from this analysis are in complete agreement with the results of Kasuya (Ref.8) who showed that spin wave exchange leads to an effective repulsion in the case of electrons with opposite momenta and spins in the neighbourhood of the Fermi surfa--e. It is shown that electron-magnon interaction prevents the transition to superconducting states. There are 8 references. 5 Soviet and 3 Non-Soviet). ASSOCIATION: Urallskiy gosuniversitet im.

This is brought into connection with the d- and f-shells of the electron sheath. The electron density of the transition metals is divided into three regions. The first is near the nucleus, the second consists of the valence electrons, and the third intermediate region consists of the electrons of the non-closed shells. For this system the Hamiltonian (i) is written down.

It was established that the absence of cat- alysts~does-in no way cbanpe the tetraethylsilane hydro.-en even at a tempera- ture of 5000. A temperature much higher than 5000 results in the pyrolysis of the tetraethylsilane and the formation of elementary Si and sortie gaseous pro- ducts. At a temperature of about 5500 the tetraethylsilane is split, by thu hydrogen over an A12(SiO3) catalyst forming triethylsillane and ethane.. The mechanism of destructive hydrogenation of tetraethylsilane is explained. Sev- en references: 3-USA; 2-German;.1-French and l-USSR (1904-1950). Tbies. Institution : The A. A.

ABSTRACT: Experiments shoved that ethyl silicic other in the presence of a homologous sodium phenolate reacts easily with phenols of different structures. This reaction was considered to be very simple and also suitable for the synthesis of tetrasroxysilanes with yields of about 70 - 85%. By employ- ing this reaction method, the authors synthesized eleven tetraaroxysilanes as well as orthosilicic ethers of cyclohexanol, cy-clopentanol and benzyl alcohol. The physico-chemical properties of the tetraaroxysilanes obtained are dezeribed in a table. When exposed to ultraviolet light, all tetra- Carcl 1/2 aroxysilanes give a light blue or dark blue as well as a violet fluorescence.
