Magnetic Properties of the semimagnetic semiconcuctor Zn0.40Mn0.60Ga2Se4
Keywords:
Semimagnetic semiconductor, Brillouin funtion, magnetization curves, magnetic susceptibilityAbstract
We report on some of the magnetic properties of the semimagnetic semiconductor alloy Zn0.40Mn0.60Ga2Se4 which belongs to the semimagnetic semiconductor alloy system Zn1- x MnxGa2Se4. The analysis of the magnetization curves indicates that for temperatures 4,2 below K the system is in the antiferromagnetic phase (AF), whereas for T>4,2 K the system is in a paramagnetic phase (P). From the M vs. H curves the susceptibility response was calculated for T= 2, 4,2 and 10 K. The analisys showed an antiferromagnetic interaction between the Mn+2 ions with Curie–Weiss temperature q » -13.4 K and not all the Mn+2 ions contribute to the magnetization.
