EPR and magnetic properties of vapour phase grown Zn1−xCrxTe crystals

The EPR and magnetic properties were investigated on vapour phase grown Zn1−xCrxTe (0.001⩽x⩽0.0050.001⩽x⩽0.005) crystal samples at room temperature. The EPR spectra were observed for samples with x=0.001x=0.001, 0.002 only. The simulations of the spectra confirm Cr3+ charge state of the dopant ion at tetrahedral symmetry. The magnetic behaviour of the samples with x=0.001x=0.001 and 0.002 is neither that of Brillouin paramagnets nor Van Vleck systems while the samples with compositions x=0.003x=0.003, 0.004 and 0.005 exhibited hysteresis behaviour.
