Measurements of the de Haas-van Alphen (dHvA) extremal areas for the magnetic field in seven nonsymmetry crystallographic planes have been performed in Pd. All three sheets of the Fermi surface expected from band-structure calculations were observed, and the agreement between the calculated and observed surfaces is satisfactory. The shapes of the surfaces are, on the whole, very similar to those in Pt. An area-to-radii inversion has been accomplished for the Γ-centered electron surface and the number of carriers was determined by numerical integration. Effective-mass measurements were performed in four nonsymmetry crystallographic planes. The anisotropy of the observed effective masses for the Γ-centered surface is radically different from Pt, thus showing that although the surfaces are quite similar in shape, the underlying band structures (velocities) are quite different. Effective masses determined from band-structure calculations are shown to be consistent with the experimental values if renormalization effects are taken into account. Masses on the heavy open-hole surface are found to be more enhanced than those on the Γ-centered surface. Spin-splitting zeros are observed for all three sheets of the surface. Assuming that the g factor approximates its free-space value of 2. 0, we can determine precise values of the g factor at these spin-splitting zeros by using interpolated effective-mass values. On the whole we find the g factor to be somewhat different from 2. 0 and anisotropic. Measurements on 0. 1 and 0. 05 at.% Co in Pd have revealed the existence of exchange splitting in the energy bands associated with these alloys. This has been confirmed both from the disappearance of the spin-splitting zeros and from the observation of beat waists arising from the area shift between the spin-up and spin-down exchange split bands.
