Increasing Magnetic Anisotropy in Bimetallic Nanoislands Grown on fcc(111) Metal Surfaces

Harald Brune, Stefano Rusponi, Sergio Vlaic, Dimitrios Mousadakos

The magnetic properties and the atomic scale morphology of bimetallic two-dimensional nanoislands, epitaxially grown on fcc(111) metal surfaces, have been studied by means of Magneto-Optical Kerr Effect and Scanning Tunneling Microscopy. We investigate the ...

Low Temperature Ferromagnetism in Chemically Ordered FeRh Nanocrystals

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser, Sergio Vlaic, Alberto Cavallin

In sharp contrast to previous studies on FeRh bulk, thin films, and nanoparticles, we report the persistence of ferromagnetic order down to 3 K for size-selected 3.3 nm diameter nanocrystals embedded into an amorphous carbon matrix. The annealed nanopartic ...

Magnetism and Atomic Scale Structure of Bimetallic Nanostructures at Surfaces

Sergio Vlaic

his thesis reports on the magnetic properties of bi- and tri-metallic nanostructures at surfaces. The main goal is to build the smallest nanostructure ferromagnetic at room temperature and the assembly of those structures in high density arrays. To this pu ...

Atomic-scale engineering of magnetic anisotropy of nanostructures through interfaces and interlines

Harald Brune, Stefano Rusponi, Philipp Buluschek, Sergio Vlaic, Géraud Moulas

The central goals of nanoscale magnetic materials science are the self-assembly of the smallest structure exhibiting ferromagnetic hysteresis at room temperature, and the assembly of these structures into the highest density patterns. The focus has been on ...

Self-Assembled Nanometer-Scale Magnetic Networks on Surfaces: Fundamental Interactions and Functional Properties

Klaus Kern, Harald Brune, Stefano Rusponi, Pietro Gambardella, Anne Lehnert, Sergio Vlaic, Sebastian Stepanow

Nanomagnets of controlled size, organized into regular patterns open new perspectives in the fields of nanoelectronics, spintronics, and quantum computation. Self-assembling processes on various types of substrates allow designing fine-structured architect ...
