Giant Nonreciprocity of Surface Acoustic Waves enabled by the Magnetoelastic Interaction
Piyush J. Shah, Derek A. Bas, Ivan Lisenkov +3
Nonreciprocity, the defining characteristic of isolators, circulators and a wealth of other applications in radio/microwave communications technologies, is in general difficult to…

Spin-orbit torque and spin pumping in YIG/Pt with interfacial insertion layers
Satoru Emori, Alexei Matyushov, Hyung-Min Jeon +8
We experimentally investigate spin-orbit torque and spin pumping in YFeO(YIG)/Pt bilayers with ultrathin insertion layers at the interface. An insertion layer of Cu…

Interfacial spin-orbit torque without bulk spin-orbit coupling
Satoru Emori, Tianxiang Nan, Amine M. Belkessam +6
An electric current in the presence of spin-orbit coupling can generate a spin accumulation that exerts torques on a nearby magnetization. We demonstrate that, even in the absence…
