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, Vf.c.c, in the MnSbM film annealed at 300°C was significantly more than estimated value. (3) The off-diagonal part of dielectric tensor, εxy´, of MMnSb with the f.c.c. phase played a dominant role in the MO Kerr effect
