Abstract

Soft X-ray magnetic circular dichroism (XMCD) measurements were performed at the L3 edge of manganese for MnFeP0.78Ge0.22 at 290 and 279 K. Temperature and magnetic field dependence of the XMCD intensity was clearly observed, which is consistent with that of the magnetization measurements as reported for the related MnFe(P,As) systems. Our results suggest that the unoccupied electronic states of Mn above the Fermi level would be modified through the first-order field-induced magnetic transition.
