The magnetic ordering of vanadium overlayers on Fe(100) was studied using spin-polarized electron-energy-loss spectroscopy. Net magnetic moments of the V surface were observed for one and two monolayers of vanadium, while no magnetic ordering of the surface was observed for thicker films. The vanadium monolayer couples antiferromagnetically to the Fe substrate, while the surface of two monolayers of vanadium aligns ferromagnetically with the substrate. The magnetic moment of the V monolayer is estimated to be less than 1μB.
