**Switching, sensing, and coupling nanomagnets enabled by spin-orbit
coupling**
_Pietro Gambardella_
_Department of Materials, ETH Zurich, CH - 8093 Zürich, Switzerland_
The spintronics landscape has changed dramatically over the last ten years.
Much of this change is due to a deeper understanding of the interactions and
charge-spin conversion processes mediated by spin-orbit coupling in different
classes of materials [1]. In this talk, I will discuss new opportunities to
sense and manipulate the magnetization of metallic and insulating nanomagnets.
Illustrative examples will focus on unusual magnetoresistance effects [2],
electrical switching of tunnel junctions [3,4] and iron garnets [5], as well
as on the emergence of chiral coupling phenomena, which enable the realization
of synthetic antiferromagnets and skyrmions [5].
