Abstract:
Single crystals of Zn1-xMnxTe for x = 0.1, 0.25, 0.45, 0.5 and 0.6 were prepared using vertical Bridgman technique. EPR (electron paramagnetic resonance) spectra were recorded at room temperature (303 K) between 0 and 6 kG magnetic field and range of frequency 8.8-9.6 GHz. As the concentration of Mn increases the line width (DeltaH) and the number of spins (Ns) were increased. Susceptibility studies were carried out at room temperature in the range of dc magnetic field 0-10 kG using vibrating sample magnetometer (VSM). Non-linear variation in susceptibility as a function of concentration (x) was observed and was explained on the basis of sp-d and d-d exchange interactions between Mn2+ ions and ZnTe lattice ions. Both EPR and susceptibility studies confirm the paramagnetic state of Zn1-xMnxTe system at RT.
