Abstract
Pressure derivatives of extremal cross sections of the Fermi surface of palladium have been determined by means of de Haas-van Alphen measurements under pressures up to 3.7 kbar. The experimental pressure derivatives are found to be in good agreement with theoretical values obtained from a self-consistent bandstructure calculation based on the linear muffin-tin orbital (LMTO) method using the local density approximation for exchange and correlation. The calculated extremal areas of the X centred Fermi surface pocket are found to be in better agreement with experiment than those obtained from the standard potential construction. The electronic Gruneisen parameter and the pressure dependence of the electron effective masses have also been calculated.
