Abstract

Antiferromagnetic layered compound CuCrS2 has been prepared in single phase. Structural details with x-ray diffraction and electronic transport properties from 15 to 300 K have been studied. X-ray diffraction with reitveld refinement gave significant concentration of Cr occupying inter-layer octahedral site. Antiferromagnetism is marginally affected by chromium disorder. The electrical resistivity in polycrystalline pellet shows non-metallic non-insulating behavior while the single crystal flake is metallic. We interpret the temperature dependence of electrical resistivity and thermoelectric power due to the localization of carriers and the formation of magnetic polarons in the paramagnetic phase of CuCrS2 due to the Cr disorder.
