Abstract

Mn/Sb multilayer films were grown on GaAs (100) by ultrahigh vacuum evaporation technique and subsequent thermal annealing for short duration. Structural, magnetic properties and magneto-optical Kerr effect were investigated. Magnetization measurements reveal strong room- temperature ferromagnetism even for unannealed films. X-ray diffraction patterns show high-quality crystal structure of MnSb is formed. The film annealed at 350 degree(s)C also shows the lowest coercivity and the largest saturation magnetization. Both the polar and longitudinal magneto- optical Kerr rotations are observable for annealed films and the dependence of the Kerr rotation angles on the magnetic field is nearly the same as that of magnetization.
