ABSTRACT

The paper reports the findings on the baric dependences of the thermoelectromotive force (thermo-emf) of the Cd3As2 + n mol% MnAs granular structures, n=10, 20, 30 and 44.7, where peculiarities in the thermo-emf behavior (extrema, inflection points on the S(P) curves or pressure hysteresis) are observed. The peaks are observed in Cd3As2 + n mol% MnAs in the pressure range P= (28-35) GPa for the cases n=10 and n=20; in Cd3As2 + 30 mol. % MnAs at P= (20-35) GPa; in Cd3As2 + 44.7 mol. % MnAs at P=(30-35) GPa. At pressures higher than 40 GPa, the thermo-emf changes weakly or practically does not vary both at increasing and subsequent decreasing pressures.

Keywords: thermoelecromotive force, electric resistance, clusters, high pressures, Seebeck coefficient, relaxation time.
