- States of magnetic and compositional order are strongly coupled in many magnetic alloys, with Ni-Fe Invar being the most celebrated example. Results of an electronic-based method that addresses compositional and magnetic disorder, as well as atomic short-range order and energetics, are discussed. This allows a system-dependent microscopic understanding of the interplay of chemical, magnetic, and displacive effects, and a direct comparison to diffuse scattering experiments. Discussion is in context of total-energy calculations for various magnetic states in chemically disordered and ordered Ni- Fe alloys, emphasizing the importance of exchange-splitting and the implication for phase stability in Ni-Fe system.
