We have focused on one of the candidates for magnetization switching devices, Mn_4-xAg_xN. In the last presentation, we demonstrated the presence of magnetic compensation composition at room temperature. We prepared 20-nm-thick epitaxial Mn_4-xAg_xN (x = 0.05 and 0.15, 0.80) films on SrTiO3(001) substrates and measured the XANES spectra to determine their preferential substitution site for Ag. In our presentation, we will discuss the magnetic structure of Mn_4-xAg_xN based on the XANES measurements.
