Abstract

The anisotropy of the g factor on all sheets of the Fermi surface of pure Pt and Pd has been investigated by studying the spin splitting amplitude vanishing of the de Haas-van Alphen effect. In all cases the g factor was observed to be anisotropic and varied by as much as 25% from its free space value of 2. Thus, estimates of the Stoner enhancement factor deduced from the calculated density of states with a g factor of 2 may be in considerable error. Evidence for the itinerant nature of the ferromagnetism in cobalt-doped palladium has been observed both from the disappearance of the expected spin splitting zeros and the beating of the frequencies derived from corresponding cross-sectional areas on the exchange split bands. An estimate of the magnitude of the exchange splitting is made from the beat frequency.
