- Abstract
- <jats:title>Abstract</jats:title> <jats:p>We investigated morphological features and magnetic properties of epitaxial Fe nanostructures (films, stripes and nanoparticles) on a W(110) surface with monoatomic steps preferentially along the <jats:inline-formula> <jats:tex-math><?CDATA $[1\bar{1}0]$?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="EM15003if001.gif" xlink:type="simple" /> </jats:inline-formula> direction. The nanostructures were prepared in ultra-high vacuum by using electron-beam evaporation and subsequent annealing at different temperatures. Scanning tunneling microscopy measurements in-situ revealed elongated Fe nanostructures with aspect ratios of up to <jats:inline-formula> <jats:tex-math><?CDATA $1:20$?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="EM15003if002.gif" xlink:type="simple" /> </jats:inline-formula>. The observable shape and orientation (along or perpendicular to the monoatomic steps of the substrate) of the nanostructures depended substantially on the preparation parameters. By capping the system with 7 monolayers of Pt, the magnetic properties of selected Fe nanostructures could be analyzed ex-situ using Lorentz microscopy revealing diversified results. Depending on the size and shape, different magnetization structures, such as single domain, two domains and vortex, were observed. A precise intensity profile analysis demonstrated that the magnetic field values of different magnetic structures are close to each other and equal 2.4 T.</jats:p>
