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