摘要 X-ray absorption near edges structure (XANES) spectra of the Diluted Magnetic Semiconductors (DMS) system Zn1-xMxS (M=Mn, Co) have been measured at the Mn and Co L3,2-edge using sample current mode. Analysis of the M L3,2-edge XANES spectra for Zn1-xMxS revealed the presence of a white line feature in each series, whose intensity increased linearly with concentration x. The white line feature is assigned to M 2p3/2 and 2p1/2 photoelectron excitations to nonbonding 3d(e) states and to the relatively broadened band of M 3d(t2) - S 3p hybridized antibonding states. The rate of increase of L3,2 white line intensity with x is associated with the difference in the degree of p-d hybridization of states between M 3d and S 3p.
