FIG. 1.

Evolution of the neutron diffraction patterns with temperature for alloy. The diffraction peaks of the FePt phase are marked; arrows indicate the position of the magnetic superstructure peaks.

FIG. 2.

Fe magnetic moment for , , and in dependence on temperature, as obtained from neutron diffraction. The continuous lines correspond to a fit using Eq. (1). Magnetic moment of iron at , , Curie temperature , and shape parameter , obtained from the fit are given in the inset.

Tables

Table I.

Parameters obtained by refinement of x-ray data: volume fraction of the phases , lattice constants and , fraction of the Pt(Fe) sites occupied by the correct atom , and order parameter . Values of the magnetic moment of iron obtained from the refinement of neutron diffraction data collected at are given together with the corresponding agreement factors. The magnetic moment of Pt was fixed at per atom.
