Magnetic correlations in CumFen/Cu(1 0 0) and ComFen/Cu(1 0 0)

Abstract We investigate magnetic correlations and local moments at finite temperatures in some FCC Cu m Fe n and Co m Fe n structures on Cu(1 0 0) substrates using an ab initio mean-field theory of magnetic fluctuations for layered materials. We find that the thermal spin fluctuations give rise to layer-dependent local moments and layer-dependent magnetic correlations which depend strongly on the structure of the films.
