Abstract
A self-consistent method to compute local magnetic moments and spin polarized electron densities of states and to test the stability of the ferromagnetic vs. the paramagnetic state is developed within the framework of the itinerant electron theory. The tight-binding Hamiltonian, with Coulomb correlation among d electrons, is parametrized according to the Slater-Koster interpolation scheme. The method goes beyond the rigid band splitting approximation. We apply it to the Fe 1− x B x amorphous system for 0 ⩽ x⩽0.6 and obtain the magnetization for T=0 as a function of x in agreement with experimental data in the experimentally-accessible concentration region.
