Surface and interface magnetic effects in CoNRhM clusters
Source abstract
Abstract
The spin moments, orbital moments, and magnetic anisotropy energy (MAE) of CO N Rh M clusters having N induced at the Rh atoms, which amount to about 20% of the moment per Co atom ( = (0.2-0.3) μB ), and to an enhancement of the orbital moments of the Co atoms at the Co-Rh interfaces. The calculated MAEs reveal remarkable changes in the easy axis as a function of concentration. The magnetic properties are analyzed from a local perspective. The role of the chemical arrangement of Co and Rh atoms within the cluster is discussed.
