Abstract
We report the spin-dependent electron momentum distribution in Mn excess Ni-Mn-Ga ferromagnetic shape memory alloys including Mn2NiGa using 176.8 keV circularly polarized synchrotron radiation at SPring8, Japan. The magnetic Compton profiles (MCP) were measured at various temperatures and magnetic fields. The data have been analyzed in terms of Mn 3d, Ni 3d and delocalized spin moments. The magnetic-moment values obtained from the MCP and the behavior of the magnetic effect R with temperature and field for the different specimens are in good agreement with our magnetization measurements.
