Title: Fluorescence XAFS Study on Local Structure around Cr Atoms Doped in ZnTe

Abstract

The geometric structures for ferromagnetic Zn1-xCrxTe films grown by molecular beam epitaxy were investigated by fluorescence XAFS measurements in order to elucidate the relationship between the geometric structure and the magnetic properties. XAFS analysis suggested that the majority of Cr atoms doped in CrTe substituted the Zn-site in the ZnTe lattice below the Cr content x = 0.048, and formed Cr-Te compounds such as Cr2Te3 and CrTe above x = 0.090. It is suggested that ferromagnetism of the Zn1-xCrxTe films above x = 0.090 is due to the formation of Cr-Te compounds.
