Peculiarities of anisotropic electrical resistivity in Lu2PdSi3 single crystals

Author affiliations

Abstract

Lu2PdSi3 represents a non-magnetic member of the class of R2PdSi3 intermetallic compounds (R = rare earths) with hexagonal AlB2-type crystallographic structure. The electrical resistivity of single crystalline Lu2PdSi3 is highly anisotropic and reflects metallic behaviour. Its temperature dependence follows the Bloch–Grüneisen law for c-axis orientation [001]. For [100] orientation in the perpendicular plane the observed deviation from the Bloch–Grüneisen law can be explained by the Ioffe–Regel criterion. The relatively low Debye temperature ΘD of the order of 200 K fairly well agrees with that derived from specific heat data of Lu2PdSi3. Notably, Lu2PdSi3 allows extracting the magnetic entropy contribution of isostructural R2PdSi3 compounds.
