Abstract
High density self-assembled Fe nanostructures are fabricated at high temperature on a Mo(110) surface by pulsed laser deposition (PLD) under ultra-high vacuum conditions. The co-deposition of an additional element is investigated to control the morphology of the nanostructures. Using a composite Sm-Fe target, 3D Fe(110) islands are obtained within a narrow temperature range, where the Sm partly evaporates from the surface due to its high vapor pressure. The co-deposition of Sm leads to an increase of the Fe island density and induces a hutch-like shape of the nano-crystals which are elongated along the [1-10] crystallographic direction with a lateral aspect ratio around 2. The magnetic behavior of the films is dominated by the shape anisotropy contribution of the individual islands. The easy axis is aligned along their larger dimension. A coercivity of 60mT is measured at room temperature for 35Onm long islands.
