摘要：

The demand for hard magnetic materials is exponentially growing, while at the same time prices of rare earth elements can not be considered as stable. Therefore, rare-earth free permanent magnets are intensively sought after. In this work we have performed a systematic study of magnetic properties of Fe3C with hexagonal and orthorhombic structures using full-potential local-orbital electronic structure code FPLO. Employing virtual crystal approximation (VCA), we also performed calculations for the composition range (Fe1-xCox)(3)C. In addition, also using VCA, we determined the dependence of magnetocrystalline anisotropy on the number of electrons in the C site, considering a range of alloys from B, through C, to N (atomic numbers 5, 6 and 7). The results obtained suggest new candidates for hard magnetic materials.
