摘要
The Shubnikov-de Haas effect in the type II3V2 diluted magnetic semiconductor alloy (Cd1-xZnxMny)(3)As-2 was investigated in the region of 0 less than or equal to y less than or equal to 0.08, x + y = 0.3. Single period oscillations of the conductivity were observed in the temperature interval of 4.2 - 31 K and magnetic fields up to 11 T. In one of the samples (y = 0.02) a well-resolved spin-splitting was seen. Values of the cyclotron effective mass and the g-factor were determined. A strong dependence of the cyclotron mass on the magnetic field was observed in crystals with a high Mn concentration.
