Improvement of magnetic hardness at finite temperatures: ab initio disordered local moment approach for YCo
arXiv:1405.5673 · doi:10.1103/PhysRevB.90.054421
Abstract
Temperature dependence of the magnetocrystalline anisotropy energy and magnetization of the prototypical rare-earth magnet YCo is calculated from first principles, utilizing the relativistic disordered local moment approach. We discuss a strategy to enhance the finite-temperature anisotropy field by hole doping, paving the way for an improvement of the coercivity near room temperature or higher.
