Abstract

We have determined the Curie temperature $T_{c}$ of an epitaxial monolayer of Fe(110) on a W(110) substrate by means of spin-polarized low-energy-electron diffraction. Adsorption of submonolayer amount of Fe causes $T_{c}$ to increase distinctly. An enhancement of $T_{c}$ by about the same amount is also found upon adsorption of submonolayers of Pd, Ag, and $O_{2}$ .
