The magnetic ordering of a series of samples consisting of ultrathin Fe layersembedded in Pd was investigated using the magneto-optical Kerr effect. Thesamples consisted of a single Fe layer with nominal thickness 0.2 dFe 1.6monolayers sandwiched between two 20 monolayer Pd layers. A dimensionalitycrossover from two dimensions to three dimensions occurs as dFe is increasedfrom 0.4 to 1.0 monolayers. First-principles calculations were performed inorder to determine the magnetic profile, and we used a spin-wave quantum wellmodel for obtaining a qualitative description of the dimensionality crossover.The results clearly prove the existence of a dimensionality crossover in theinduced magnetization, opening new routes for addressing the influence ofextension on order.
