Abstract:

We have grown films of the half-metallic ferromagnet NiMnSb on single crystals of the narrow gap semiconductor InSb by pulsed laser deposition. NiMnSb is a possible candidate for spin injection applications. The film depositions occurred at 200°C. X-ray diffraction studies indicate a high degree of (220) texture and no secondary phases. A saturation magnetization of four Bohr magnetons, μB. at 5 K and coercive fields down to 5 Oe at 300 K indicate the good quality of the films.
