Self-organisation and magnetic properties of Co nanostructures embedded in a Cu(100) surface

► We design a SLkMC technique for simulation of diffusion of embedded atoms. ► The formation of embedded Co nanostructures in Cu(100) is investigated. ► Time evolution of the surface can be divided into three stages. ► The morphology is observed at different temperatures and concentrations of Co. ► Magnetic properties of small embedded nanostructures are investigated.
