SmCo5 permanent magnets exhibit enormous uniaxial magnetocrystalline anisotropy energy and have a high Curie temperature. However, their low energy product is a significant deficiency. To increase the energy product in SmCo5, we propose substituting cobalt with iron, that has a much larger magnetic moment, in a SmCoNiFe3 magnet where nickel is used as a thermodynamic stabilizer.
