A model is developed for the band structure of the Fe 0.5 Rh 0.5 antiferromagnetic ordered alloy, and the local effects are studied of a substitutional impurity on the electronic and magnetic properties of the host. It is found that an Fe impurity substituted for Rh creates a perturbation extending at least to the nearest neighbours of the impurity, and a total ferromagnetic moment close to 3.5μ B A Rh impurity substituted for Fe has a localized and less important effect. The influence of the magnetic state of the host and the case of other impurities substituted for Rh are also investigated.
