Abstract

The hyperfine field and the isomer shift of Fe−X (X=SC, Ti, V, Cr, Mn, Co, Ni, Cu) disordered alloys are calculated by use of the Korringa-Kohn-Rostoker coherent potential approximation (KKR-CPA) combined with the density functional theory in the local density approximation. The agrements with available experimental data are fairly well if the well-known systematic discrepancy arising in the Fe hyperfine field is properly biased. The overall trends of the concentration dependence of the Fe hyperfine field is qualitatively explained in terms of the local and the transferred contributions to the hyperfine field.
