Thermoelectric Properties of a Ferromagnetic Semiconductor Based on a Dirac Semimetal (Cd3As2) under High Pressure

The pressure dependences of thermal emf (a parameter that ranks among the most sensitive to phase transformations) are studied for the purpose of identifying baric phase transitions in the 10–50 GPa interval in the Cd3As2 + MnAs (44.7% MnAs) structure formed by ferromagnetic MnAs granules in a semiconductor Cd3As2 matrix.
