Abstract: Y39.00012 : Search for the new rare-earth free iron-based permanent magnets*

We have calculated from first principles the electronic structure and magnetic properties of ferromagnetic Fe3Sn doped with Si, P, Ga, Ge, As, Se, In, Sb, Te, Pb, and Bi on the Sn sublattice as well as with the Mn phase-stabilizer on the iron sublattice. We discuss the influence of the different dopants on the magnetocrystalline anisotropies and Curie temperatures of Fe3Sn and suggest new stable/metastable ferromagnetic phases with uniaxial anisotropy suitable for the development of advanced permanent magnets.
