Magnetism and magnetocrystalline anisotropy of tetragonally distorted L1(0)-FeNi: N alloy

Popis výsledku v původním jazyce

We report the tunable magnetic properties of L1(0)-FeNi via inducing tetragonal distortion with interstitial doping. For this, we have performed full potential calculations of L1(0)-FeNi with interstitial N-doping within generalized gradient approximation. Two types of interstitial N-doping in Ni/Fe-layer of the parent alloy have been investigated. The calculated formation energy reveals the increased structure stability of tetragonally distorted FeNi via N-doping. Our calculations predict that this structural distortion induces large magnetocrystalline anisotropy at the cost of small degradation in the saturation magnetization. The increment in magnetocrystalline anisotropy is more for N-doping in Ni-layer as compared to that in Fe-layer. Hence, L1(0)-FeNi:N alloy with N addition to Ni-layer has all the qualities to be emerged out as a probable material for permanent magnets in coming years.
