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