摘要：

The structure and magnetic properties of ultrathin Mn films on fee Co/Cu(001) were studied at room temperature, using the in situ magneto-optical Kerr effect and low-energy electron diffraction. We found that a two-dimensional magnetic c(2x2) Mn-Co(001) surface alloy is stabilized in the range of 0.3-0.8 ML of Mn. Within this thickness range Mn is ferromagnetically coupled to the fee Co(001) underlayer. Above one monolayer of Mn, the c(2x2) superstructure disappears and the Mn overlayer no longer has long-range ferromagnetic order.
