Synthesis and magnetoresistance of (Cd1−x Znx)3As2 (x = 0,007) crystals

The vapor phase growth of Cd₃As₂—Zn₃As₂ (in the following (Cd_1−x Zn_x)₃As₂ solid solutions process is described. The (Cd_0,993 Zn_0,007)₃As₂ solid solution single crystals were synthesized. Scanning electron microscopy and electron diffraction data suggest high crystalline quality of studied sample. Its structure and surface morphology, indicating the presence of growth nuclei and cleavage planes, were investigated. Giant anisotropic magnetoresistance and Shubnikov — de Haas oscillations were observed at low temperatures. Obtained results suggests that peculiarities of Dirac semimetal phase persist in (Cd_1−x Zn_x)₃As₂ solid solution at low zinc content. At the same time, there are indications of some differences with initial Cd₃As₂ properties.
