Аннотация:Density functional theory and kinetic Monte Carlo method are applied in our study to describe formation, stability and magnetic properties of atom-wide wires on vicinal metal substrate. We present temperature ranges of atom-wide wires’ formation for different systems. The lifetimes of nanowires were determined, and their stability was discussed. Our calculations for both ferromagnetic Fe and Co wires decorating Pt(775) step edge show that the easy magnetization is in the plane perpendicular to the wire, while for Cu(775) it is oriented along the wire. The wire properties obtained from our simulations will be useful both for creating a new generation of materials and for explaining the experimental data.
