In this paper, we investigate the potential of tetragonal L1<sub>0</sub>-ordered FeNi as the candidate phase for rare-earth-free permanent magnets considering anisotropy values from recently synthesized, partially ordered FeNi thin films. In particular, we estimate the maximum energy product (BH)<sub>max</sub> of L1<sub>0</sub>-FeNi nanostructures using micromagnetic simulations. The maximum energy product is limited due to the small coercive field of partially ordered L1<sub>0</sub>-FeNi. Nano… CONTINUE READING
