HIGH-FIELD DEHAAS-VANALPHEN SPECTROSCOPY IN TRANSITION-METALS

We report detailed studies of the electronic properties of the high Tc superconductor niobium and the Stoner enhanced paramagnets platinum and palladium. Parametrization schemes based on the KKR method of band calculation are shown to give excellent representations of the Fermi surface properties. Agreement of the experimental Fermi radii with those of first principles band theory is very good. Local vlaues of the many body enhancements due to electron-phonon and electron-electron interaction are derived by comparison of experimental and theoretical Fermi velocities. © 1979.
