"Magnetism, spin dynamics and transport at the nanoscale"

Who: Manuel dos Santos Dias, Peter Grünberg Institut, Forschungszentrum Jülich, Germany

Place: Online Seminar, Donostia International Physics Center

Date: Thursday, 22 April 2021, 12:00

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.
