The paper is devoted to the study of induced magnetic field gyration in CdS and (GaxIn1-x)2Se3 (x=0.3) crystals in the spectral range of interband absorption. The dispersion of the magnetogyration effect is experimentally obtained. It was found the magnitude of magnetogyration depends on the value of absorption coefficient and that the circular dichroism appears with the approach of the wavelength of absorption edge. Contrary to the wide band semiconductors CdS and (GaxIn1-x)2Se3 (x=0.3) the Li2B4O7 do not possess magnetogyration as well as SiO2 crystals do not possess the magnetogyration effect due to the symmetry conditions. The observed phenomenon is explained as the result of the presence absorption, spatial dispersion and the existence of the external magnetic field. In such a case the found effect is not contradiction to the Onzager principle.

Key words: magnetogyration, interband absorption, dichroism, Faraday effect
