Calculation of Anisotropy Energy for γ-Mn

Abstract

The anisotropy energy for antiferromagnetic γ-Mn with collinear structure is calculated by using the new method improved by us based on Gilat and Raubenheimer’s one. It is shown that it is sufficient to take the channel width 10⁻⁴ Ry and the number of mesh points 1872 in 1/6 of BZ for this calculation. Some discussion is given for the magnetic structure with the canted spin.
