Abstract : |
The magnetization of the diluted semimagnetic semiconductors (DMS) Zn1-xMnxTe, x = 0.02, 0.05, 0.10, 0.20, and 0.60, is measured in the temperature range 4.2 to 30 K, the magnetic field varying from 0 to 5 T. It is compared with the magnetization of Cd1-xMnxSe and Cd1-xMnxTe measured earlier for the same temperature and magnetic field ranges. The measured magnetization is fitted with a phenomenological Brillouin function using a least-squares method, with S0 and T0 as fitting parameters. The saturation spin value S0 is found to decrease with increasing manganese concentration for all the three series and a qualitative increase as a function of temperature is observed. However, T0 did not show any quantitative or qualitative features as a function of either Mn concentration or temperature., |
