Abstract! Of 315 patients with digestive bleeding, 50~1' had gastro-
dGodenal bleeding. Digestive bleeding in acute form presents a
serious medical problem which requires effective and urgent
therapy. One part of the problem is tehnical, the necessity to
provide hospitalization and sufficient amounts of blood for the
patients. The second part of the problem is the differing
attitudes between the surgical and internal departments as.to how
and where to treat the patients. It is necensar7 . to provide
close coop6ration between surgeon and kimmist in all cases where
the illness can be treated by both* No references.

a variable circularly polarized field oriented perpendicular to the constant field
and rotating with a frequency w much less than c1r, where r is the linear size of
the body. It is shown that msonance phenomena may also be observed when the vari-
:able magnetic field rotates in a direction opposite to that of free precession.

can be achieved if I exceeds specimen length by 2D. It is noted:that experimental

TEXT,;- The distribution of Barkhausen jumps incident to tension (in three
principal directions) was measured in single-crystal and polycrystalline specimens
of cold-rolled steel (3% Si). At the same time, domain structure was studied by
means of powder figures. It was found that Barkhausen jumps appear not only as a
result of irreversible boundary shifts due to the presence of nonmagnetic enclaves
and stresses, but also as a result of the rebuilding of domain structure that takes
place incident to application of stresses and during remagnetization.

an improvement on the one given by A. 14. Rodichev, N. I-11. Salanskiy, and V.' I.
Sinegubov (Izv. SO AN SSSR ig6o, No. 31 123). The duration had a threshold of 0-5
microseconds, and the time constant of the apparatus was'below 0.3 microsecondse.
An NGPK generator was used to measure the intensity of the magnetic field. The
revorsible parmoability was measured'by the superposition of an extremely small
alternating field of amplitude 10-2 - 10-3oerstdg. Experiments were also performed

ABSTRACT: The Barkhausen effect is usually~tudied by measuring the
emf induced in a coil surrounding the ferromagnetic
specJ.Lmen., The enif pulses induced in this coil by dis-
continuous changes in the magnetization are the only source
of information about,this phenomenon, The time interval
between successive pulses can be made quite large by a
suitable choice of the linear dimensions of the specimen
and the rate of change in the magnetic field H . Under
such conditions each emf pulse corresponds to a single
discontinuity. The present paper is concerned with the
determination of the relationship between the pulse
parameters and the volume of.the region in the ferro-
magnetic within which the discontinuous change in the
magnetization takes place, the increase in the magnetization,

of the process, etc. It is shown that the only physical
characteristic which can be found directly from.the
observed induced emf is the change in the dipole moment
In0 which is proportional to the tine integral of the
induced emf. It follows that it is desirable to include
an electronic integrator in'the usual apparatus employed
to measure the Barkhausen effect. A formula is obtained
(Eq 21) which expresses the emf induced in the measuring
coil as a function of the change in the magnetic dipole
moment of a region in a ferromagnetic cylinder at an
arbitrary distance from its axis. The formula is similar
to that obtained by Tebble et al (Ref 3) but its derivation
xs more rmsorous. The theoretical calculations are compared
with published experimental results. There are 12 figures
and 11 references, 8 of which are Soviet, I German and

TEXT: This paper was presented at a conference on magnetism and antiferro--
magneti3m~ The dynamics of the domain boundaries was studied by investi-
gating the large Barkhausen jumps in thin (1500 to 2000 1) iron and Fe-Nii-
Mo vacuum condensed films, with a magnetic field directed along the base.
Some of these films underwent complete magnetic reversal in one Barkhausen
jump, The measurements were made with a monolayer measuring coil no, 1
(length 10 mm, winding diameter i mm, 328 turns) and with two 3eries-connm..
ted coils no. 2 (length 0.2 mm, 100 turns each). The authors were able to
make experiments similar to those of Sixtus and Tonks (Ref. 1, see below)
and to study the field dependence of the rate of propagation v of the oppo-
sitely magnetized domain, For magnetic reversal in fields lower than H c

artificial nuclei must be created. This was done by means of an addition-
al coil. The v value determined was not in agreement with the orate of
boundary migration L, as the boundary is not at an angle of 90 to the
direction of displacement. To determine L and, consequently, also the
parameter of elastic damping P, which determines the losses due to bounda-
ry migration, the exact shape of the boundary must be knovrp. The proportio-
nality of v to (H - H ) found is equivalent to the proportionality between
0
and(H - H0) as the shape of the boundaries did not change during the
movement, Both v and H 0 depend on the shape of the boundary, itself.depen-
dent on the method by which the nucleus was created. The dependence of H 0
on imperfections and material defects was studied in Fe-Ni-Mo films. The
study of large Barkhausen jumps may be of great practical importance since
the hysteresis loops of the substances subject to magnetic reversal in one
jump, are highly orthogonal. There are 5 figures and 4 non-Soviet referen-

ABSTRACT: The purpose of the work was to obtain the ideal magnetization curve for a
cilicon iron single crystal and to thvestigdte its domain structure in equilibrium
states corresponding to different values of the external field. The purpose of the
experiments'was to check the thermodynamic theory of V.A.Ignatchenko, I.F.Degtyarev
and Yu.V.Zakharov (Izv.AN SSSR,Ser.tiz.25,12,1961), which predicts, for a case of
this type, decrease in the total number of domains and decrease in the width of the
disadvantageously oriented domains. Tho 3.5%.Si iron single crystals were etched
and polished on two sides and armealed tollowing the standard procedure. The di-

mensions of the specimens were 10 x'40 x 0.15 ma; this size was deliberately chosen
to be close to the values used In the numerical calculations performed in the above
mentioned reference. The plane of the specimens was parallel to within 1-30 to the
(110) planes and one of the sides was aligned with the 100 direction. The exter-
nal field was applied in this direction. From among the 80 prepared specimens
there were selected four with uniform plane-parallel domain structure over the on-
tire specimen. The equilibrium states were obtained by demagnetization with a gra-
dually decreasing alternating field in the presence of the desired constant field.
Photographs of the domain structure are reproduced. The experimental results can-
firm the theoretical prediction of decrease in the number of domains with increase
of the applied field. The average domain width versus field curve is also close to
the theoretical curve. The ideal magnetization curve obtained from ballistic measur
ments Agrees with the magnetization curve plotted on the basis of the doma-in areas.

ABSTRACTs By means of the powder patterns by Akulor, Dekhtyar, and
Bitter (Ref 1) in the present paper the effect of elastic
strain on the domain structure of the crystals of cold-
rolled transformer sheet iron (3,4% Si) was investigatedd
It was shown that the domain struoture changes considerably
when a strain is applied. The character of these changes
depends on the orientation of the stress. on the crystal
surface that coincides with the plane (110) the powder
pattern has the form of parallel lines. These lines have
the direction of the axis of the weak magnetization which is
next to the surface. This speaks for the fact that the
Card 1/4 domain structure consists of plane-parallel layer domaine.

These layer domains are oriented in the direction of the
powder lines and are magnetized in the same direction. The
plane-parallel layer domains never exhibit the same width
in one and the same sample. The application Of the stress
to the sample compensates for the wholg tension in the
sample and thus Also for the domain st-cucture. During
strain application sometimes a separation ofthe layer
domains into two halves can be observed. This separation
comes as a consequence of new boundaries, (Fig 1). It must
be mentioned that the remagnetization of a number of domains
is not caused by the dislocation of -the boundary but
apparently by a sudden inrersion of whole domains. Tensions
that are directed along the axis (110) in the crystal
completely rebuild the original structure of the domains.
If the stress is sufficiently high two new types of figures
appear (Fig 2). For reasons of comparison also finely
crystalline samples-with a linear grain dimension of 1
1,5 mm. were observed. A more or less simple law connecting
the width and the magnitude of the stress could not be found.

As was observed, the domain structure char,jes when the stress
is oriented along the direction of the complex magnetization
as well as when it is directed along the axis of the weak
magnetization. In crystals the surface of which.coincides
with the plane (100).a change of the domain structure of the
closed type was observed when a strain was applied. Re-
productions of powder patterns show that the layered struature
of the ferromagnetic domains.,must.eyhibit closed domains
for excluding the formation of free stray-fields. The
powder pattern method alone is not perfect and may be
applied more-successfully if it is combined with another
method. In the present paper apart from observations of
powder patterns also the Barkhausen (Barkgauzen) jumps were
roe-orded. Figure 4 shows the results. There are 4 figures
and 2.references, 1 of which is Soviet.,
