Abstract
In order to tune the magnetocrystalline anisotropy (MCA) of L10-FeNi by introducing tetragonal distortion, we have investigated FeNi with interstitial C-doping using full-potential approach within generalized gradient approximation (GGA). Our calculations foretell that these structural distortions of FeNi result in a large MCA of 1.88 MJ/m3 at the cost of small suppression in saturation magnetization. Moreover, calculated formation energy also promotes the structural stability of FeNi:C over FeNi. Hence, L10-FeNi:C alloy has the potential to act as opportune rare-earth free permanent magnetic material.
