Magnetic properties of NiMnSb(001) films grown on InGaAs/InP(001).
Journal of Applied Physics 95 (11, Pa), pp. 7462-7464.
NiMnSb half Heusler alloy films were prepared by molecular beam epitaxy (MBE) on InP(001). The dc and rf magnetic properties were investigated
by ferromagnetic resonance (FMR). The effective uniaxial anisotropy
fields increased with increasing film thickness and reached nonzero
asymptotic values. FMR linewidths rapidly increased with the film
thickness due to the presence of two magnon scattering. Bulklike
uniaxial anisotropies and two magnon scattering were caused by a
self-assembled network of lattice defects. Gilbert damping parameter
and spectroscopic g factor were found to be 3.1x10(7) and 2.03,
respectively, indicating a weak role of spin orbit interaction. (C)
