Magnetotransport of (Cd1?x?yZnxMny)3As2 under Pressure

Linear dispersion of Dirac fermions in (Cd1–x–yZnxMny)3As2, х+y = 0.2, у = 0.02, 0.04, 0.06, 0.08 solid solutions

“…The observation of Shubnikov-de Haas (SdH) oscillations while investigating the magnetoresistance of CZMA single crystals allowed us to define the effective mass of charge carriers and compare the Shubnikov, n Sh , and Hall, n h , charge carrier concentrations. In CZMA single crystals, this ratio was close to unity, which indirectly indicated the quality of the studied single crystals [9][10][11][14][15][16].…”

“…Diluted magnetic semiconductors obtained in the А 2 В 5 group have previously received the attention thanks to their special properties [5]. In the early stage of research, single crystals of (Cd 1-x-y Zn x Mn y ) 3 As 2 (CZMA) quaternary solid solutions were investigated without sufficient regard for their topological properties [10,11]. CZMA solid solutions has the potential to become extremely useful in the development of electronic devices using twodimensional electron gas [12,13].…”

“…CZMA solid solutions has the potential to become extremely useful in the development of electronic devices using twodimensional electron gas [12,13]. For the effective use in electronic appliances, it is essential to determine the characteristics of charge carriers not only as it was done in [10,11], but also taking into account topological properties, notably in recent works devoted to these materials [9,[14][15][16].…”
