Electrical properties in the region of magnetic phase transition of TlCoSe₂ compound

ABSTRACT

TlCoSe₂ compound was obtained by direct synthesis from pure Tl, Co and Se elements. The electrical conductivity and thermo-emf coefficient of the obtained compound were studied in the temperature range of 77-400K. It was determined that at antiferromagnetic T_N=85K and ferromagnetic T_C=150K temperatures of this sample, there is an anomaly in electrical conductivity and thermo-emf coefficient in phase transitions. This is explained by the scattering of spins with interlayer antiferromagnetic alignment and then ferromagnetic alignment within the layer.

Keywords: magnetic phase transition, conductivity, thermoelectric motive force
