Abstract

The results of calculations of the electronic structure, thermoelectric characteristics, and an experimental study of the thermoelectric, electrical, and optical properties of Mn2MeAl Heusler alloys (Me = Ti, V, Cr) are presented. The agreement between theory and experiment in the sign of the Seebeck coefficient is shown. The obtained pattern of the band spectrum allows us to qualitatively explain the peculiarities of the temperature dependences of the electrical resistance and the permittivity dispersion.

Keywords

Heusler alloys, electronic structure, Seebeck coefficient, electrical resistance, optical properties
