The effective g factors of states on all sheets of the Fermi surface for fcc paramagnetic nickel, palladium and platinum have been considered. Calculations have been carried out using both the combined interpolation scheme and the Symmetrized Relativistic Augmented Plane Wave (SRAPW) methods. Corrections due to the outside of the muffin-tin spheres potential (included for Pd and Pt) are shown to be small. Strong spin quenching in all three systems is caused by combination of the close proximity of the dominant X5 and L3 (single group representation) levels to the Fermi energy and the raising of their degeneracies by the important spin-orbit interaction. Comparisons with the experimental data, in particular static susceptibility and dHvA orbital g factors, are presented.
