Ferromagnetic stability in Fe nanodot assemblies on Cu(111) induced by indirect coupling through the substrate

We report collective ferromagnetic behavior with high Curie temperatures (T(c)) in Fe dot assemblies supported by the Cu(111) surface. Our ability to tune the average size and spacing of the individual dots allows us to conclude that enhanced magnetic anisotropy cannot account for this high-T(c) fer...
