Abstract

The effect of low-powered polarized light on magnetic characteristics of ferrimagnetic garnet films has been studied by means of polarization microscope. The spectral, polarization, temperature and intensity dependences of room- temperature photomagnetic effect have been obtained. Correlation of magnetization and domain structure changes with parameters of the film and illuminated light are discussed in terms of developed model. Mechanism of the effect is connected with a photoinduced strain of the crystal lattice.
