    We have theoretically investigated thermodynamic properties of random iron–cobalt monolayer deposited on the fcc(001) face of copper. The effective twodimensional Heisenberg Hamiltonian was constructed from first principles and used to estimate the Curie temperature by the random-phase approximation as well as Monte Carlo simulations. Calculations predict a weak maximum of the Curie temperature for Fe-rich composition of the overlayer.
