Ab Initio Study of the Oxygen Effect on Magnetic Interactions within 3d Metal Nanowires on Vicinal Rh (553) Surface
We present ab initio study of the magnetic properties of monatomic 3d transition metal (Mn, Fe, Co, Ni) nanowires without and with oxygen atoms on vicinal Rh (553) surface. We considered different experimentally observed submonolayer quantities of oxygen atoms. It was found that monatomic 3d metal nanowires without oxygen are in magnetic states. Within oxidized metal nanowires oxygen atoms affect on the magnetic moments and magnetic interaction of metal atoms. This influence leads to reduced (in the case of Mn, Fe and Co atoms) or quenched (in the case of Ni atoms) magnetic moment for these metal atoms.
