Abstract
For the disordered fcc alloy FexNi1−x, we study the dependence of the Curie temperature, average and local magnetic moments on the concentration x. We show how the dependence of the average and local magnetic moments on the concentration changes with temperature. The problem is considered in the renormalized Gaussian approximation of the dynamic spin-fluctuation theory. The numerical results are in good agreement with the experiment.
