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…
Ultra-fast artificial neuron: generation of picosecond-duration spikes in a current-driven antiferromagnetic auto-oscillator
Roman Khymyn, Ivan Lisenkov, Jamie Voorheis +5
We demonstrate analytically and numerically, that a thin film of an antiferromagnetic (AFM) material, having biaxial magnetic anisotropy and being driven by an external spin-transf…
Bias-free spin-wave phase shifter for magnonic logic
Steven Louis, Ivan Lisenkov, Sergey Nikitov +2
A design of a magnonic phase shifter operating without an external bias magnetic field is proposed. The phase shifter uses a localized collective spin wave mode propagating along a…
