Abstract
A kinetic Monte Carlo method was used to perform large-scale simulation of one-dimensional magnetic nano-structures on vicinal metal surfaces. Temperature ranges for nanochains’ formation were obtained for different systems. The lifetimes of the nanochains were determined, and their stability is discussed. The dependence of chain lifetime on its length is not linear. In order to be usable at room temperature, magnetic Co chains should have a length of 25–30 atoms.
