Title: Thermodynamics of SmCo 5 compound doped with Fe and Ni: An ab initio study

Abstract

SmCo 5 permanent magnets exhibit enormous uniaxial magnetocrystalline anisotropy energy and have a high Curie temperature. Furthermore, their low energy product is a significant deficiency. In this paper, to increase the energy product in SmCo 5, we propose substituting cobalt with iron, that has a much larger magnetic moment, in a SmCoNiFe 3 magnet where nickel is used as a thermodynamic stabilizer.
