“…Measurements were made on the pulsed magnetic field facility in the temperature range from 1.6 K to 300 K and the magnetic fields from 0 to 25 T. The SdH oscillations observed in the CZMA samples are shown in Figure. Increasing of an amplitude of the SdH oscillations in the investigated samples (Cd 0.6 Zn 0.36 Mn 0.04 ) 3 As 2 and (Cd 0.6 Zn 0.32 Mn 0.08 ) 3 As 2 with at increasing a magnetic field is similar to that observed earlier for other CZMA compositions [10,11].…”

“…where P SdH is the period of the SdH oscillations, the ratio n R /n SdH is close to unity, in accordance with results obtained previously for CZMA [10,11,13]. When considering the properties of solid solutions of (Cd 1-xy Zn x Mn y ) 3 As 2 , we were based on the similarity of the band structure of Cd 3 As 2 and InSb [16].…”

“…For both samples the value of the cyclotron effective mass of charge carriers m c , Shubnikov n SdH and Hall n R concentration, mobility, µ H , of charge carriers and period of oscillations P SdH , were defined (Table). The obtained parameters do not conflict with similar results obtained previously for diluted magnetic semiconductors CZMA (x+y = 0.2; x+y = 0.3) [10,11,13]. This work was supported by the Russian Science Foundation (grant №17-12-01345) in the part of crystal growth and structure characterization.…”

Abstract. Single crystals of a diluted magnetic semiconductor (Cd 1-x-y Zn x Mn y ) 3 As 2 (CZMA) (х + y = 0.4;у=0.04 and 0.08) obtained by Bridgman method were used. The Shubnikov-de Haas (SdH) effect was observed within studying of the dependence of the resistivity on the magnetic field in CZMA solid solutions. The values of the cyclotron mass m c , Hall and Shubnikov carrier concentrations were calculated.

“…The galvanomagnetic properties of the narrow-gap n-type diluted magnetic semiconductor (DMS) (Cd 1± ±x± ±y Zn x Mn y ) 3 As 2 , briefly CZMA, have been investigated (i) in the vicinity of the gapless state for |E g | < 0.1 eV [1] and (ii) relatively far from it, at E g % 0.27 eV [2,3], by changing the gap E g with variation of the composition. In the latter case, corresponding to x + y = 0.3, the anomalous magnetic field dependence of the electron effective mass, m(B) = m(0) + aB where m(0)/m 0 = 0.03 to 0.05 and a/m 0 = (8 to 15) Â 10 ± ±3 1/T, has been observed.…”
