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…

Sub-terahertz ferrimagnetic spin-transfer torque oscillator
Ivan Lisenkov, Roman Khymyn, Johan Akerman +2
A theory of magnetization dynamics in ferrimagnetic materials with antiparallel aligned spin sub-lattices under action of spin-transfer torques (STT) is developed. We consider magn…

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…
