Title: Magnetic properties of DyCo{sub 5} and TbCo{sub 5} intermetallics from the electronic structure calculations

Abstract

LSDA and LSDA+U calculations, with spin-orbit coupling (SOC) included, were performed for DyCo{sub 5} and TbCo{sub 5} intermetallic compounds. In the case of magnetic moments, LSDA-SOC calculations give results in good agreement with the experimental data. However, LSDA has shown to be unable to predict relative stabilities of ferromagnetic and ferrimagnetic configurations of the 4f and 3d spin sublattices giving the wrong result that the ferromagnetic configuration is more stable. LSDA+U method cures this problem and gives correct result. Additionally, within the accuracy of available experimental data, the corresponding effective exchange fields are in reasonable agreement with experiment.
