Abstract
Electrical resistivity ρ, Hall factor RH, magnetic resistance (Rm–R0)/R0, and magnetic-field-dependent resistances were measured in 70 mol % Cd3As2 + 30 mol % MnAs composite at fixed values of high hydrostatic pressures (up to p ≤ 9 GPa). The ρ, RH, and (Rm–R0)/R0 versus pressure curves feature a phase transition at p = 4–4.3 GPa. Field-dependent magnetic resistance features a negative pressure-induced trend.
