摘要：

Recent in situ polarized neutron-reflectometry and magneto-optical Kerr effect measurements have displayed a few magnetically dead Fe layers deposited on V(110). We have performed ab initio density-functional theory calculations in order to explain the a priori unexpected results. An ideal layer-by-layer growth of Fe on the V(110) surface leads to the ferromagnetic solution for every Fe thickness. However, if alloying is present at the interface, a strong decrease in the Fe magnetization is found. We discuss the different magnetic configurations and the possible mechanisms that can produce the observed magnetically dead Fe layers.
