Abstract :
The photoinduced changes of the magnetization vector orientation under the optical linearly polarized irradiation (λ=0.53 μm and λ=1.06 μm) were observed in ferromagnetic films (YCa)3(FeCoGe)5O12. The effect is a result of the occurrence of the photoinduced anisotropy. The phenomenologic description based only on general symmetry consideration is suggested
