Abstract

The discrete variational method and the local exchange approximation were used to calculate the electronic structure of 19 atom embedded clusters representing Fe-Ni alloys of fcc structure. Magnetic moments and hyperfine fields were derived from the calculations and compared to experiment. We find that the observed reduction of H_c compared to pure iron is not due to reduced Fe moments, but instead due to a change of sign of the conduction electron (4s) contributions.
