Electronic structure calculation on thermoelectric behaviour of Mn2CoPt

Abstract

The electronic structure of Mn₂CoPt, which crystallizes in rock-salt structure, has been computed using FP-LAPW method within the density functional theory. Since Mn₂CoPt belongs to Heusler compounds family, therefore it becomes important to understand its thermoelectric behaviour. Heusler compounds are known to have good power factor for their use in thermoelectric generators. Further, Mn₂CoPt was found stable in ferromagnetic state with high magnetic moment of 9 _B. In this regard, Mn₂CoPt was investigated in reference to its electronic profile, electrical conductivity, Seebeck co-efficeint and power factor.
