Abstract

The MO (Magneto-Optical) Kerr effect for the Mn₅₁Sb₄₃M₆ (M=Pt, Au and Pd, and Mn:51at%, Sb:43at% and M:6at%) films was discussed from the viewpoints of the structure and dielectric tensor analyses. It was clarified; (1) The Mn₅₁Sb₄₃M₆ films after annealing at 300°C were found to consist of MnSb with the hexagonal phase and MMnSb with the f.c.c. phase. (2) The volume fraction of MMnSb with the f.c.c. phase, V_f.c.c, in the MnSbM film annealed at 300°C was significantly more than estimated value. (3) The off-diagonal part of dielectric tensor, ε_xy´, of MMnSb with the f.c.c. phase played a dominant role in the MO Kerr effect
