Abstract
In this work, combining experimental results and first principles calculations, we show that interstitial nitrogen not only serves for inducing tetragonality in Fe8Nx but is also essential for achieving a high degree of perpendicular magnetocrystalline anisotropy, K. Our results demonstrate that the orbital magnetic moments of the iron atoms above and below N in the direction of magnetization are much more susceptible to the applied magnetic field than their in-plane counterparts, leading to a giant value of K as compared to a hypothetical distorted material without N.
