摘要：
Surface alloy formation of Mn on Co(001) was detected by low-energy electron diffraction and in situ magneto-optic Kerr effect experiments. Here we discuss the electronic and magnetic properties of an equivalent Mn monolayer (ML) at the surface of Co(001) using the tight-binding linear muffin-tin orbitals method. Magnetic configurations and stability of ordered 2D Mn-Co alloy 2 ML thick vs Mn/Co(001) and Co/Mn/Co(001) have been considered. Multiple magnetic configurations have been always obtained but a comparison between the ground states display an instability of the perfect Mn ML on Co(001). Total energy differences are considerably reduced in the case of spin-polarization calculations as compared with the non-magnetic one. (C) 1000 Elsevier Science B.V. All rights reserved.
