Magnetism and magnetocrystalline anisotropy of tetragonally distorted L10-FeNi: N alloy

We report the tunable magnetic properties of L10-FeNi via inducing tetragonal distortion with interstitial doping. For this, we have performed full potential calculations of L10-FeNi with interstitial N-doping within generalized gradient approximation. Two types of interstitial N-doping in Ni/Fe-lay...
