Magnetization dynamics of mixed Co–Au chains on Cu(110) substrate: Combined ab initio and kinetic Monte Carlo study |
The time-average magnetization | M | (white circles) and the central difference derivation –d| M |/d T (black circles) as a function of temperature T . The Au–Co chain consists of 100 atoms of cobalt. The parameters of the Heisenberg Hamiltonian are J = 5.125 meV and K = 3 meV. |
