Metallic and molecular nanostructures on well-defined surfaces
The present thesis is concerned with the growth of nanostructures on well-defined metal substrates. Four experimental chapters address various effects, which occur upon deposition of molecules and/or
Fe on Sb(111): Potential Two-Dimensional Ferromagnetic Superstructures.
This work reports on two superstructures including a honeycomb-like lattice and identical nanocluster arrays formed by depositing Fe on Sb(111) using first-principles calculations, which provide a method to fabricate 2D magneticsuperstructures possessing great potential in the realization of the Haldane model, spintronics applications, and single atom catalysis.
Geometrical Effects on the Magnetic Properties of Nanoparticles.
This work investigates how geometry can influence the magnetic properties of nanoparticles, focusing in particular on platinum clusters of 1-2 nm in size, and finds that the total magnetization depends strongly on the local atomic arrangements.
Dipolar magnetism in assembled Co nanoparticles on graphene.
The results suggest an efficient route to stabilize the ferromagnetic phase of nanostructures on graphene by tailoring dipolar interactions, which is essential to realize a higher efficiency of spin injection in graphene-based spintronics.

Magnetic properties of planar nanowire arrays of Co fabricated on oxidized step-bunched silicon templates.
Thickness dependent magnetization studies reveal that the magnetization reversal is governed by the curling mode reversal for thick wires whereas thinner wires exhibit a more complex behaviour which is related to thermal effects and size distribution of the crystal grains that constitute the NWs.


Magnetism of Low-dimensional Metallic Structures
The chapter “Magnetism of low-dimensional metallic structures” reviews experiments on the magnetism of surface-supported low-dimensional structures of 3d metals. Controlling the static and dynamic
Observation of a complex nanoscale magnetic structure in a hexagonal Fe monolayer.
It is demonstrated that the complex magnetic structure observed is induced by the strong Fe-Ir hybridization, which is lower in energy than all solutions of the classical Heisenberg model.
Growth of low-dimensional magnetic nanostructures on an insulator
Iron nanometer-scaled wires and ultrathin films have been successfully prepared on an insulating NaCl(001) single-crystal surface by electron beam deposition using different growth conditions. In
Supramolecular control of the magnetic anisotropy in two-dimensional high-spin Fe arrays at a metal interface.
It is shown that the supramolecular assembly of Fe and 1,4-benzenedicarboxylic acid molecules on a Cu surface results in ordered arrays of high-spin mononuclear Fe centres on a 1.5 nm square grid, opening a way to control the magnetic anisotropy in supramolescular layers akin to that used in metallic thin films.
The remarkable difference between surface and step atoms in the magnetic anisotropy of two-dimensional nanostructures
A method enabling the identification of the remarkably different contributions of surface and perimeter atoms to the magnetic anisotropy energy of two-dimensional nanostructures is introduced, using the generally nonlinear relationship between perimeter length and surface area.
