Ab initio Disordered Local Moment Approach for a Doped Rare-Earth Magnet

DOI DOI オープンアクセス

説明

Following the finite-temperature ab initio calculation framework based on the relativistic disordered local moments, we computationally demonstrate the possibility of doping-enhanced coercivity at high-temperatures, taking YCo$_5$ as a working material in order to extract the $3d$-electron part of the electronic structure of the rare-earth permanent magnets. Alkaline-earth dopants are shown to be the candidates to realize the proposed phenomenon.
