EFFECT OF PRESSURE ON THE ELECTRICAL-RESISTIVITY AND LATTICE-CONSTANT OF CEPD3

The temperature dependence of the electrical resistivity ρ{variant}(T) of the mixed valent compound CePd3 has been measured under hydrostatic pressure up to 15 kbar. It is found that the resistivity-maximum temperature, Tm, increases with increasing pressure. The result is shown to be consistent with that of the pressure dependence of coefficient of the T2 term in ρ{variant}(T). The lattice constant a is measured at high pressure up to ca. 150 kbar at room temperature. Since a shows a smooth variation against pressure, there is no change in crystal structure and no volume collapse at least up to 150 kbar. © 1990.
