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…
Low Power Microwave Signal Detection With a Spin-Torque Nano-Oscillator in the Active Self-Oscillating Regime
Steven Louis, Vasyl Tyberkevych, Jia Li +6
A spin-torque nano-oscillator (STNO) driven by a ramped bias current can perform spectrum analysis quickly over a wide frequency bandwidth. The STNO spectrum analyzer operates by i…
Antiferromagnetic THz-frequency Josephson-like Oscillator Driven by Spin Current
Roman Khymyn, Ivan Lisenkov, Vasyl Tiberkevich +2
The development of compact and tunable room temperature sources of coherent THz-frequency signals would open a way for numerous new applications. The existing approaches to THz-fre…
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…
Interaction of microwave photons with nanostructured magnetic metasurfaces
Ivan Lisenkov, Vasyl Tyberkevych, Luke Levin-Pompetski +4
A theoretical formalism for the description of the interaction of microwave photons with a thin (compared to the photon wavelength) magnetic metasurface comprised of dipolarly inte…
Theoretical formalism for collective spin-wave edge excitations in arrays of dipolarly interacting magnetic nanodots
Ivan Lisenkov, Vasyl Tyberkevych, Sergey Nikitov +1
A general theory of edge spin wave excitations in semi-infinite and finite periodic arrays of magnetic nanodots existing in a spatially uniform magnetization ground state is develo…
Transformation of spin current by antiferromagnetic insulators
Roman Khymyn, Ivan Lisenkov, Vasil S. Tiberkevich +2
It is demonstrated theoretically that a thin layer of an anisotropic antiferromagnetic (AFM) insulator can effectively conduct spin current by excitation of a pair of evanescent AF…
Acoustic wave propagation in fluid metamaterial with solid inclusions
Ivan Lisenkov, Roman Popov, Sergey Nikitov
Acoustic waves propagation of in composite of water with embedded double-layered silicone resin/silver rods is considered. Approximate values of effective dynamical constitutive pa…
