Abstract
The electrical resistivity (rho), magnetic susceptibility (chi) and th ermoelectric power (S) of PtGa2 were measured as a function of tempera ture (T). This compound is metallic at high temperatures, as shown fro m the room temperature resistivity value (19 muOMEGA cm) and the linea r dependence of the S vs T curve at temperatures above the Debye tempe rature (theta(D)). The density of states (DOS) at the Fermi energy (E( F)) at high temperatures obtained from chi and S data agree to within 22% and 15%, respectively, of the value obtained previously from a sem iempirical band structure calculation.
