Effect of Hydrostatic Pressures of up to 9 GPa on the Galvanomagnetic Properties of Cd3As2–MnAs (20 mol % MnAs) Alloy in a Transverse Magnetic Field

We have studied the effect of hydrostatic pressure on the galvanomagnetic properties of a Cd3As2 + 20 mol % MnAs alloy in a transverse magnetic field of up to 4 kOe. The pressure dependences of the Hall coefficient and resistivity for the alloy provide evidence of reversible phase transitions. The observed negative magnetoresistance of the alloy is shown to be induced by high pressure.
