Electrical Resistivity, Magnetic Susceptibility and Thermoelectric Power of PtGa2

Abstract

The electrical resistivity (p), magnetic susceptibility (X) and thermoelectric power (S) of PtGa2 were measured as a function of temperature (T) . This compound is metallic at high temperatures, as shown from the room- temperature resistivity value and the linear dependence of the S vs. T curve at temperatures above the Debye temperature. It undergoes a superconducting phase transition with a critical temperature (Tc) at zero magnetic field of 2.13K. The density of states (DOS) at the Fermi energy (EF) at high temperatures obtained from X and S data are 22% and 15% higher, respectively, than the value obtained previously from a semi-empirical band-structure calculation.
