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
