Magnetic Moment Distribution in Ferromagnetic Co?Mn Alloys

Abstract

Using the magnetic environment model, the moment distributions for ferromagnetic COl_xMnx alloys in the composition range (0 < x < 0·25) were calculated from the mean saturating moments of the alloys. The calculation also gives the mean moment of each species as a function of concentration. The predictions correspond extremely well with the existing experimental data. In particular, the increase in the correlation length close to the ferromagnetic critical concentration is clear in the cross section data and model.
