Abstract:
(ZnS)1-x(MnTe)x luminescent powder samples with x=0.02, 0.05, 0.10, 0.15, 0.20 and 0.25 were prepared by solid-state reaction method. EPR spectra were recorded at room temperature (300K) in the frequency range 8.8-9.6GHz for samples of all compositions. The line width (DeltaH) and the number of spins increased with MnTe concentration. Room temperature dc magnetic susceptibility measurements were carried out using vibrating sample magnetometer. Susceptibility of the samples increased with MnTe content.
