Paper Abstract

This work presents our attempts to grow thin films of the ferromagnetic half-Heusler alloy NiMnSb and also a bi-layered structure MnSb/NiMnSb onto (100) semiconductor substrates using Single Beam and respectively Double Beam Pulsed Laser Deposition. We investigated the samples by XRD, scanning electron microscopy (SEM), Energy Dispersive X ray (EDX) analysis and SQUID magnetometry. The thin films obtained in both configurations are crystalline, single phase with stoichiometry corresponding to the bulk material. The out of plane magnetisation of the bi-layered structure reaches the saturation value more rapidly than the NiMnSb/Si film.
