TITLE: Magnetic Properties of Tourmaline PERIODICAL: It Kristallograflya, 1959, Vol 1, Nr 6, PP 873-877 (USSR) ABSTRACT: Magnetic properties of tourmalines depending on their chemical composition and color were studied. Previous works in this field are briefly reviewed. Measurements of the specific mass magnetic sus- ceptibilities (Xm) of green, black,and pink tourmalinea were taken on the radio freqiaency unit described previously (V. M. Vinokurov, Kristallograftr4 3,5, 600, 1958). Results of the measurements of specific mass magnetic susceptibilities of black tourmalines (schorls) are given In Table 1, those .of the green tourmalines in Table 2, and those of the Card 1A_ 2 pink tourmalines in Table 3. masnetic Properties of Tourin-aline 77111 soy/7o-4-6-12/31 The following conclusions, from the data obtained, were madp.

B111XI02 resonator was used. The crystal in it could rotate around an axis perpendi- cular to the resonator's axis. The magnet rotated together with it by 3600. The measuremonta showed that the angular dependence of the e.p.r. 3+ spectrum was due to paramagnetic atoms substituting the Al ions. The direction c was found to be one of the main directions of the electric field in the crystal acUng on the paramagnetic ion. Whilst the existence of four magnetically nonequivalent, pairwise identical complexes was expected from X-ray diffraction studies, investigations of the e.p.r. spectra indicated the existence of on3y two identical complexes oriented in opponite directions. The orientations of ';he other two include an angle of about 700 The authors attempt to explain t.iis divergence by the assumption that the Ai3+ions are replaced by Fe3+ only in those complexes (II and IV in Fig. 1) in which the A13+ions are arrangil symmetrically around the 0 2- ions. If one considers only the neighborho.-,-l of the substituting Fe3+ions, they seem to be subjected to an almost cubica.-.y symmetric el.,ctric field. It is, however, shown that the spectrum observr.:. can be descritad by a Hamiltonian of lower (rhombical) symmetry.

The authors of the present "Letter to the editor" examined this problem theoretically and showed that all experimental results concerning paramagnetic resonance spectra and spin-lattice relaxa- tion time can be easily explained. For Ti in corundum an anoLialoualy large = 1.067, g anisotropic factor (g, 1< 0.1) has been measured, and the spin- lattice relaxation time Ti did increase from Ti - 5-10- 8 to 0.1 sec in the Card 1/3 69229 S10561611040100110351037 Theory of the paramagnetic*.. B102/B212 transition from 9 to 1.55 0K. If it is assumed that the trigonal component of the crystal field has a much stronger spin-orbit interaction, and if the cubic and trigonal components are considered at the same time, and, moreover, if the constant of the trigonal field is taken to be negative, then it is possible to explain those data. The spin-orbit interaction splits the 1 orbital gTound level into two Krameral spin doublets (interval S = 70 om and one obtains g, = 0 and g, - 1.07. If the importance of the covalent coupling between the metal ion and the surrounding oxygen atoms is taken into account then one finds that gfor the Ti ion has to be somewhat dif- ferent from zero. Considering the very strong spin-lattice i~-teraction one obtains, due to the main role of two-phonon processes: T -T- .

B102/B212 being taken into account, the change being such that the initial splitting of the spin quadruplet is 2D - 24 am- 1; (S - 3/2). It has been established experimentally that the spin-lattico coupling of Co 21 ions is much atrongar at 250K than that of Cr3+ ionsl at helium temperatureal conversely, T 1 of Cr3+ ions was much shorter than Ti of Cc 24 ions. This can be also explained if we consider that at higher than helium temperatures the spin-lattice coupling will be strong and is governed by tWO-Dhonon processes, while at temperatures below helium temperature it will b; governed by single-phonon processes which are related to transitions between spin-levels of the lower Kramers doublet.

Expressions are given for the openitors which describe the fine structure of the spectra for various types of electric field symmetry: cubic hexagonal, triagonal,, tetragonal, rhombic and purely axial. The procedures used for absorption line identification to find the constants of the spin Hiuniltonian are dis- cussed. Expressions are given for calculating the hyperfine structure due to inter- action between the electron magnetic moment and the magnetic moment: of the nucleus of the paramagnetic atom. Experimental research done at the Kazan Unfversity an electron paramagnetic resonance spectra in crystals is briefly reviewed. The data on ions with identical effective spins are grouped together. Ions with spins of: 1/2, 3/2, 5/2 and 7/2 are considered. Orig. art. has: 25 figures, 30 tables, 30 formulas.

Experimental and theoretical studies of EPR of Cr3+ and Gd3+ in a number of different supercooled solutions and glasses were conducted at frequencies of 100 , Mhz. It is shown that the weak field condition obtains at these frequencies. The theo retical interpretation is based on an assumption that the rhombie component of the ' spin Hamiltonian is large compared to the others. A good agreement between calculated values and experimental data was obtained.

The crystals with lithium showed an Fn spectrum (at 9.3 G11z) with a line structure having 5, 7, and 3 com- ponents when the field was parallel to the z, x, and y axes,respectively. The lumi- nescence sDectrum of the same crystals had an intense band with maximun at 7860 A, a weaker band at 6805 A, and narrow lines at 7320 and 7620 A. The levels corresponding to these lines are identified. In the case of the copper impurity, the same EPE and optical spectra were observed but with lower intensity. In addition, a more com,- plicated EPR spectrum with new lines due to several centers is observed. In the crys- tals with Wa impurity or those without any impurity, the EPR spectra observed in the Card ~/2 UDC: none ACC NRI AP7005679 crystals with lithium vanishes, and only the complicated EFR spectrum obserred with copper is seen. The maximum at 6805 A in the optical spectrum becomes stro er. The results do not lead to any unique conclusions other than that the excess Cr charge is compensated by the Up Ila, or Cu in a nonlocal manner.
