Abstract

The ferromagnetic behavior in two-dimensional Fe dot assemblies on the Cu(111) surface that persists above room temperature was discussed. To tune the average size and spacing of the dots enables one to investigate the relative contribution of the mechanisms that support the robust magnetic order. It was found that by growing assemblies of magnetic dots which had a fixed average size and varied spacing and then monitoring the resulting influence on the magnetic behavior. The results show that enhanced magnetic anisotropy cannont account for high Curi temperature (T_c) ferromagnetic orders.
