X-ray absorption near edge structure (Xanes) studies of diluted magnetic semiconductors (dms) zn1-xyxs (y=mn, fe, co) systems
X-ray absorption near edge structure (XANES) spectra of the Diluted Magnetic Semiconductors (DMS) system Zn1-xMnxS have been measured at the Zn Lnjn-edges and of Zn1-xMnxS (Y = Mn, Fe, Co) at the S K-edge using total electron yield mode. The Zn Lm-edge results for Zn1-xMnxS reveal a dramatic reduction in intensity of the first prominent feature, just above the edge, in the XANES spectra. Analysis of the S K-edge XANES spectra for Zn1-xMnxS revealed an increase in a pre-edge peak and a corresponding decrease in the first above-edge peak with increase in transition metal content in the alloys. These results are consistent with more S 3p- transition metal (Y) 3d(t2) hybridized states and less S 3p- Zn 4(s, p) and S 3p-Zn 3d hybridized states becoming available as transition metal content increases in the alloys.
