Enhancement in magnetic parameters of L10-FeNi on Pd-substitution for permanent magnets

In order to analyze the effect of Pd substitution on the overall electronic and magnetic properties of L1 0 -FeNi, ab-initio calculations have been performed using density functional theory (DFT) approach within generalized gradient approximation. The magnetocrystalline anisotropy for pristine FeNi...

Description
Summary:In order to analyze the effect of Pd substitution on the overall electronic and magnetic properties of L1 0 -FeNi, ab-initio calculations have been performed using density functional theory (DFT) approach within generalized gradient approximation. The magnetocrystalline anisotropy for pristine FeNi is low (  M s /2 and κ  > ½, is found to be achieved. Consequently, the Pd-substituted FeNi alloys become the potential materials for rare-earth free permanent magnets.
