Diffuse scattering intensity near the Bragg reflection in a (para)magnetic bulk face-centred cubic Ni₃Fe-type permalloy

Within the scope of the classical theoretical models, the diffuse scattering intensities (caused by the short-range atomic order) near the Bragg reflection in a (para)magnetic bulk face-centred cubic Ni₃Fe-type permalloy are investigated, taking into account the long-range magnetic order and `strain-induced' effects. The analytic azimuthal and nonanalytic `radial' behaviours of the diffuse intensities as well as the `mixing' energy Fourier components are analysed in detail.
