Structure and MO Kerr effect for MnSbM (M=Pt,Au,Pd) films

The MO (Magneto-Optical) Kerr effect for the Mn/sub 51/Sb/sub 43/M/sub 6/ (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 Mn/sub 51/Sb/sub 43/M/sub 6/ films after annealing at 300/spl deg/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/sub f.c.c/, in the MnSbM film annealed at 300/spl deg/C was significantly more than estimated value. (3) The off-diagonal part of dielectric tensor, /spl epsiv//sub xy/', of MMnSb with the f.c.c. phase played a dominant role in the MO Kerr effect.
