Ii. Davidenko et al., THE PHENOMENOLOGICAL THEORY OF A SPIN REO RIENTATION INDUCED BY THE LINEAR-POLARIZED LIGHT IN YTTRIUM-IRON-GARNET WITH SILICON, UKRAINSKII FIZICHESKII ZHURNAL, 39(5-6), 1994, pp. 736-739
The phenomenological description of an induced anisotropy and photoind
uced spin-reorientation transitions in magnetic crystals of yttrium ir
on garnet is given on the basis of the most general symmetry considera
tions only. The theoretical results are in good agreement with the kno
wn experimental data.
