摘要：

The magnetic phase of thin Fe overlayers on top of a Rh(001) surface has been probed using the surface magneto-optical Kerr effect. Quite surprisingly, we have found a suppression of ferromagnetic order up to six atomic layers of Fe. Not until Fe coverage reaches above seven layers does a ferromagnetic order start to develop. The suppression of ferromagnetic order is attributed to the tetragonally distorted cubic structure, which has been predicted to favor anitiferromagnetic ordering from our first-principles calculation using the full potential linearized augmented plane-wave method.
