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. 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 [1-3], ultrafast switching of magnetic dots and tunnel junctions [4-7], as well as chirally coupled spin lattices, synthetic skyrmions, and antiferromagnets [8].
