摘要：

We report systematic first-principles calculations based on the full-potential linearized augmented plane wave method for 3d transition-metal (V, Cr, Mn, Fe, Co, Ni) monolayers on the W(001) surface. We predict that V, Cr, and Mn monolayers exhibit a ferromagnetic ground state, while Fe and Co favor the c(2 x 2) antiferromagnetic state. This trend is surprising as it is opposite to what was expected from the knowledge of magnetism in ultrathin films and results from strong hybridization at the W interface. In particular, this system is the first case showing antiferromagnetic Co.
