抄録

The element-specific magnetization profile in the Mn75 Ir25 / Co70 Fe30 exchange bias system was studied by x-ray resonant magnetic reflectometry using circular polarized soft x rays. From the analysis of reflectivities obtained at Co L3 and Mn L3 absorption peak, we found the uncompensated Mn spins located at the MnIr/CoFe interface and in the MnIr bulk region which couples antiferromagnetically and ferromagnetically to the Co spin, respectively. A "pinned" Mn spin which does not rotate with the Co spin was observed at the MnIr/CoFe interface.
