Minority-spin band parameters in a NiMnSb thin film determined by spectral conductivity
(2004)NiMnSb is expected to be a ferromagnetic half metal, an expectation that is based in part on band structure calculations. Here we report optical conductivity studies of the band structure for a film prepared by pulsed laser ...
