Abstract

Structural and magnetic properties of substituted L10 compounds are investigated. Focus is on L10 structures of the general type ABC2, where each second layer of the original structure is replaced by a checkerboard of A and B atoms. At low temperatures, L10 compounds with ABC2 stoichiometry will segregate into AC and AB L10 phases, forming an ordered ABC2 compound or exhibit a transition into a more complicated structure. The ordering has a strong impact on the magnetism of the alloys, especially on the anisotropy. The hypothetical new ternary compounds are of potential interest in various areas of magnetism, including magnetic recording and permanent magnetism.
