Abstract

Evaluating prospects for new transition-metal-rich and lanthanide-free permanent magnets, we calculate the magnetocrystalline anisotropy of dilute Co_1-xPt_x and Co_1-xPd_x alloys. The ab initio calculations are done by using the full-potential linear augmented plane wave method, treating exchange and correlation within the generalized gradient approximation. The anisotropy contributions, 11.9 kJ/m³ per at. % Pd and 10.8 kJ/m³ per at. % Pt, are in a range suitable for permanent magnets application.
