Abstract
- Shubnikov-de Haas (SdH) effect and magnetoresistance measurements of single crystals of diluted II-V magnetic semiconductors (Cd1-x-y Zn x Mn y )3As2 (x + y = 0.4, y = 0.04 and 0.08) are investigated in the temperature range T = 4.2 ÷ 300 K and in transverse magnetic field B = 0 ÷ 25 T. The values of the cyclotron mass m c, the effective g-factor g*, and the Dingle temperature T D are defined. In one of the samples (y = 0.04) a strong dependence of the cyclotron mass on the magnetic field m c(B) = m c(0) + αB is observed. The value of a phase shift close to β = 0.5 indicates the presence of Berry phase and 3D Dirac fermions in a single crystals of (Cd1-x-y Zn x Mn y )3As2 in one of the samples (y = 0.08).
