In this talk, I will cover some highlights of my research on computational
materials modelling of magnetic nanostructures. First, I will discuss
magnetism at the atomic limit, in connection to scanning tunnelling microscopy
and spectroscopy experiments. Single atoms can be manipulated and assembled
into various nanostructures on surfaces, with fine control over their magnetic
interactions, and probed and stimulated by tunnelling electrons. This allowed
us to map the spatial dependence of the Dzyaloshinskii-Moriya interaction and
to uncover a new family of chiral interactions, to realize magnetic
bistability in small clusters, and to explore the interplay between magnetism
and superconductivity. Then I will turn to the magnetic properties of magnetic
/ heavy metal bilayer heterostructures. I will explain how we describe the
magnon spectrum in ferromagnets and how this is generalized to
antiferromagnets and more complex magnetic structures, such as skyrmions.
