Abstract:The electronic densities of states for partially ordered Ni,Fe are calculated within the framework of the Hartree-Fock and coherent potential approximations. The four-sublattices Hubbard model with an ansatz simplifying the hopping part of the Hamiltonian is used.Im Rahmen der Hartree-Fock-Ngherung und der CPA werden die Zustandsdichten fur teilweise geordnetes Ni,Fe berechnet. Ein Vieruntergitter-Hubbard-Model1 mit einem Ansatz, der den Hoppingteil dcs Hamiltonians vereinfacht, wird bcnutzt.
