Abstract

Polycrystalline samples of (GaSb)₁₀₀ _{– x}(MnSb)_x composites with x = 69.2, 52.0 and 31.7 mol %, MnSb, Mn₂Sb compounds were synthesized and their magneto-optical properties in the equatorial (transverse) Kerr effect geometry were studied. The difference of magneto-optical spectra for related compounds MnSb and Mn₂Sb is shown. The anomalous temperature behavior of the magneto-optical signal in the composites and MnSb with decreasing temperature is associated with a redistribution of the population of d-states with the opposite spin index.
