nanoGUNE Colloquium: Switching, sensing, and coupling nanomagnets enabled by spin-orbit coupling ** ** **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]. **References** [1] A.
