Electronic structure and magnetism in disordered bcc Fe alloys

Abstract

We here study electronic structure and magnetic properties of bcc Co${}_x$Fe${}_{1-x}$, Cr${}_x$Fe${}_{1-x}$ and Mn${}_x$Fe${}_{1-x}$ in their ferromagnetic phases using Augmented Space Recursion technique coupled with tight-binding linearized muffin tin orbital (TB-LMTO) method. We make a systematic study of magnetic properties like magnetic moment and Curie temperature and try to draw some conclusions on their variation across the row of 3-{\it d} transition metal series in periodic table using arguments based on effects like charge transfer, exchange splitting and hybridization.
