Ls. Hsu et al., ELECTRICAL-RESISTIVITY, MAGNETIC-SUSCEPTIBILITY AND THERMOELECTRIC-POWER OF PTGA2, Journal of physics and chemistry of solids, 54(8), 1993, pp. 913-917
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.
