Abstract—The electrical resistivity and Hall factor in n-CdAs₂, p-ZnAs₂, and n-Cd_xZn_{1 x}As₂ were measured
at hydrostatic pressures up to 9 GPa and quasi-hydrostatic pressures up to 50 GPa at room temperature. For
n-CdAs₂, a phase transition was discovered at p = 5.5 GPa; for p-ZnAs₂, two phase transitions were discovered:
one at P = 10–15 GPa and the other at p = 35–40 GPa. No anomalies were found on (p) and R(p) curves for
Cd_xZn_{1 x}As₂ when p 9 GPa.
