Abstract

The magnetic and electronic structure of Mn in In_0.965 Mn _0.035 Sb ferromagnetic semiconductor thin film was studied by x-ray absorption spectroscopy and x-ray magnetic circular dichroism. Comparison with atomic multiplet calculations suggests that manganese substitutes on sites with tetrahedral symmetry. Strong magnetic dichroism was observed from 5 to 300 K, at an applied field of 2 T. The temperature dependence of dichroism indicates presence of two magnetic Mn species having very similar spectral features. A high temperature species dominates the dichroic response over 50-300 K and a low temperature species is observed below 50 K.
