Chemical synthesis and magnetic properties of dilute magnetic ZnTe:Cr crystals

摘要

ZnTe and Cr doped ZnTe crystals have been synthesized using a solvothermal process. The characterizations by x-ray diffraction and transmission electron microscopy show that the synthesized ZnTe:Cr crystals have a cubic structure and Cr is incorporated into ZnTe. The magnetic properties of ZnTe:Cr are investigated. A hysteresis is observed in the magnetization versus magnetic field measurements below 10 K. The detailed analyses suggest that the hysteresis possibly originated from the magnetic short-range ordering of Zn_(1-x)Cr_xTe compounds in the sample.
