Abstract

We combine sensitivity to atomic number, chemical shifts, probing depth, and magnetic order in a field-dependent magnetic circular X-ray dichroism study at the Mn L-edge of the diluted ferromagnetic semiconductor Ga _1-xMn_xAs and observe different Mn constituents: ferromagnetic Mn with an nd>5 lineshape and paramagnetic Mn with distinct nd=5 lineshape. The paramagnetic Mn is assigned to interstitials with surface segregation tendency.
