“…Magneto-optical visualization of the domain structure of these crystals, as well as its evolution under the action of mechanical stresses, external magnetic field, and temperature, was used as the main method for studying orientational phase transitions in REFG. In addition, the dynamics of domain walls, magnetic hysteresis loops, and the magnetic susceptibility of REFG were studied using the Faraday effect [10][11][12][13][14][15][16][17][18].…”

A model of the rearrangement of the domain structure of the Tb0.2Y2.8Fe5O12 garnet ferrite in the temperature region of the spontaneous reorientation of the easy magnetization axis is proposed, which makes it possible to consistently describe (at a qualitative level) the entire set of experimental results obtained. The latter makes it possible to make a choice in favor of the fluctuation mechanism of nucleation of domains of a new magnetic phase in the process of reorientation of the direction of the easy magnetization axis.

“…The specimen DS was visually observed by means of a transmission polarizing microscope by using the procedure described in Ref. 5 To produce MMS in FeBO 3 :Mg, the conditions of its existence revealed previously [4] were reproduced: The specimen was cooled to Т < T s ≈ 130 K and magnetized with a field Н oriented in the (111) plane along the difficult axes. In the photoelectromagnetic experiment, the specimen cooled to Т = 80 K was additionally illuminated by a beam of nonpolarized white light of intensity 5·10 -2 W/cm 2 (a KGM12-100 incandescent lamp served as a light source) focused on the specimen surface.…”

An effect of nonpolarized white light on the modulated magnetic structure of a FeBO 3 :Mg single crystal, which arises in this light-plane weak ferromagnet in the low temperature range during technical magnetization, has been revealed. It has been found that the degree of the light action on the magnetic state of FeBO 3 :Mg depends both on its duration and on the orientation of the spontaneous magnetization vector M of the crystal during illumination. Interpretation of the results obtained has been performed in the context of the "magnetic ripple" theory on the assumption that the absorbed light induces additional uniaxial magnetic anisotropy in the easy plane of the crystal and that the anisotropy axis is collinear to the vector M during illumination.

“…In this regard, direct visual observations of the domain structure (DS) of a thin single crystal Tb3Fe5O12 terbium garnet ferrite garnet in the temperature range [3,4], including its magnetic compensation temperature (Tc = 248,6 K [5]), were carried out, the results of which are presented below.…”

The domain structure of a thin single crystal plate of the iron garnet Tb3Fe5O12 has been investigated using the magneto-optical method in the temperature range near the magnetic compensation point of this ferrimagnet Tc = 248.6 K. It has been shown that, when the temperature of the sample approaches the magnetic compensation point, the domain width significantly increases, but remains finite at T = Tc. The magnetic H-T phase diagram determines the boundary between the multi domain and domain free (uniformly magnetized) states of the sample. Here the magnetic H-T phase diagram has been constructed using the data on visual observations of the transformation of the domain structure with variations in the temperature and external magnetic field.
