Abstract

The de Haas-van Alphen effect has been used to study the extremal areas, cyclotron masses, and spin-splitting zeros on all three sheets of the Fermi surface of platinum. For the T-centered electron surface and X-centered hole pocket, newly developed inversion techniques have been employed to obtain the Fermi radius and Fermi velocity at all points on these surfaces. By performing the appropriate integrations over these surfaces, we have been able to determine the number of carriers and the density of states for these surfaces. Our observations on the open-hole surface, when combined with band-structure calculations, confirm the shape and connectivity of this surface. By combining effective-mass data with spin-splitting zero data, we have obtained information on the magnitude and anisotropy of the g factor on all surfaces. In general, we find the g factor to be different from 2.0 and quite anisotropic. The effective-mass measurements, when compared with band-structure calculations, indicate an enhancement of approximately 30%.
