Abstract
The density of states and local density of states for ferromagnetic Ni-Cu alloys are calculated in the coherent potential approximation. The Hubbard model is assumed and the Hartree-Fock approximation is used. The calculated densities of states for alloys are found to be strongly smoothened out by a rather large potential difference between Ni and Cu atoms. From the calculated results of the density of states, bulk and local magnetic moments and low temperature specific heat coefficient γ are calculated. Moreover, the high-field spin susceptibility at 0 K is calculated. These results are compared with the experimental ones and a qualitative agreement is obtained.
