摘要：
Thermoelectric properties of composites consisting of antiferromagnetic MnTe as inclusion and Fe2TiSn Heusler alloy as a thermoelectric matrix were studied. Samples of Fe2TiSn + xMnTe (x = 0, 2, 4, and 6 wt.%) were obtained by mixing Fe2TiSn and MnTe powders in planetary mill and subsequent consolidation by Spark Plasma Sintering. Measurements of thermoelectric properties revealed a decrease of thermal conductivity with an increase in the mass fraction of MnTe in the studied composites, which was ascribed to the enhanced phonon scattering at the matrix/inclusion interfaces. However, due to the decrease in the electrical conductivity and the Seebeck coefficient, the thermoelectric figure of merit ZT is significantly reduced in the studied composites.
