Abstract
The de Haas-van Alphen effect has been used to investigate the exchange splitting on the X-ellipsoid sheet of the Fermi surface of Pd and dilute Pd(Fe) and Pd(Ni) alloys. In pure Pd the g-factor shows appreciable anisotropy which can be explained in terms of the spin-orbit interaction and an isotropic Stoner enhancement. In the alloys an extra ferromagnetic exchange splitting is found. In Pd(Fe), at 2K, this is saturated at fields of order 3 T while in Pd(Ni) it varies linearly with field and decreases with increasing temperature between 1 and 2K. A striking but unexplained feature is the complete absence of spin-dependent scattering in Pd(Fe).
