Band Calculations for Non-Collinear Spin Arrangementsin Gamma-Phase Manganese-Iron Alloys

Abstract

We perfomed total-energy band calculations for Mn, FeMn, Fe 3 Mn and Fe in gamma phase. In the calculations, we dealt with not only a collinear spin arrangement but also non-collinear spin arrangements in the local density approximation. Apart from gamma-Fe and FeMn, we obtained reasonable results in the ground-state spin arrangement and magnetic moments.
