Abstract

Results are presented of a detailed relativistic augmented plane wave (RAPW) study of the magnetic field induced conduction electron polarization, magnetization density, and neutron magnetic form factor of Pt metal. We find that the spherical part of the total induced spin density is very localized spatially and almost entirely d-like in character, with the band 6 contribution differing substantially from its counterpart in Pd metal. The spin only estimate of the Weiss-Freeman asymmetry parameter is large (93% t_2g and 7% e_g). Our predicted Fermi surface dimensions for both the electron and hole surfaces (and the suitably enhanced effective masses) show excellent agreement with the recent measurements of Dye et al.
