Abstract

Electronic specific heat of Pd is deduced from the experimental data. Using the density of electronic states of Pd which has been determined from the low temperature specific heat data of Pd–Ag and Pd–Rh alloys and Ru metal by assuming the rigid band model, the electronic specific heat and the spin paramagnetic susceptibility of Pd are calculated at arbitrary temperatures. The calculated result for the temperature dependence of the electronic specific heat of Pd satisfactorily agrees with the experimental result, whereas the calculated values for spin paramagnetic susceptibility are considerably smaller than the observed values. The main difference will be attributable to the effect of the molecular field. The maximum in observed magnetic susceptibility at about 80°K can be explained by considering a peculiar band shape. Similar calculations to those for Pd metal are performed for Pd–Ag and Pd–Rh alloys.
