Abstract

The mechanism of the MO effect for the Mn₅₀Sb₄₄Pt₆ film was discussed from the viewpoints of the structure and optical properties. As results, it was clarified; (1) the Mn₅₀Sb₄₄Pt₆ film after annealing at 300°C was found to consist of MnSb with the ordered NiAs phase and PtMnSb with the disordered f.c.c. phase. (2) The resonancelike MO Kerr effect at about 2.1 eV was the unique character only for the Mn₅₀Sb₄₄Pt₆ film. (3) For the Mn₅₀Sb ₄₄Pt₆ film after being annealed at 300°C the maximum of θ_K at around 2.1 eV, where ε_xx´ was relatively small, originated from ε_xy´
