Electronic structure and magnetism of disordered bcc Fe alloys

We study the electronic structure and magnetic properties of disordered bcc Co x Fe 1-x , Cr x Fe 1-x and Mn x Fe 1-x alloys in their ferromagnetic phases using the Augmented Space Recursion (ASR) technique coupled with the tight-binding linearized muffin tin orbital (TB-LMTO) method. We calculate t...

Summary:We study the electronic structure and magnetic properties of disordered bcc Co x Fe 1-x , Cr x Fe 1-x and Mn x Fe 1-x alloys in their ferromagnetic phases using the Augmented Space Recursion (ASR) technique coupled with the tight-binding linearized muffin tin orbital (TB-LMTO) method. We calculate the density of states and magnetic moment of these alloys to show the variation upon alloying Fe with the other neighbouring 3 d transition metals using arguments based on charge transfer, exchange splitting and hybridization effects.
