Gy. Guo et H. Ebert, AN AB-INITIO INVESTIGATION OF THE HYPERFINE FIELD ANISOTROPY IN FE AND CO MULTILAYERS, Journal of magnetism and magnetic materials, 156(1-3), 1996, pp. 289-290
The magnetic hyperfine fields in several Fe and Co multilayers have be
en calculated for both in-plane and perpendicular magnetization by usi
ng a relativistic band structure method. The anisotropy in the hyperfi
ne field is pronounced and is connected with the large anisotropy in t
he orbital and magnetic dipole moments.
