Injection locking of multiple auto-oscillation modes in a tapered nanowire spin Hall oscillator
Kai Wagner, Andrew Smith, Toni Hache +8
Spin Hall oscillators (SHO) are promising candidates for the generation, detection and amplification of high frequency signals, that are tunable through a wide range of operating f…
Spin superfluid Josephson oscillator
Yizhou Liu, Igor Barsukov, Ilya Krivorotov +2
The magnetic analogue of the Josephson effect can be exploited to develop a new class of nano-spin oscillators that we denote as spin superfluid Josephson oscillators. Such a devic…
Ultra-fast wide band spectrum analyzer based on a rapidly tuned spin-torque nano-oscillator
Steven Louis, Olga Sulymenko, Vasyl Tyberkevych +7
A spintronic method of ultra-fast broadband microwave spectrum analysis is proposed. It uses a rapidly tuned spin torque nano-oscillator (STNO), and does not require injection lock…
Magnetization reversal driven by low dimensional chaos in a nanoscale ferromagnet
Eric Arturo Montoya, Salvatore Perna, Yu-Jin Chen +4
Energy-efficient switching of magnetization is a central problem in nonvolatile magnetic storage and magnetic neuromorphic computing. In the past two decades, several efficient met…
Giant resonant nonlinear damping in nanoscale ferromagnets
I. Barsukov, H. K. Lee, A. A. Jara +7
Magnetic damping is a key metric for emerging technologies based on magnetic nanoparticles, such as spin torque memory and high-resolution biomagnetic imaging. Despite its importan…
Spintronic nano-scale harvester of broadband microwave energy
Bin Fang, Mario Carpentieri, Steven Louis +15
The harvesting of ambient radio-frequency (RF) energy is an attractive and clean way to realize the idea of self-powered electronics. Here we present a design for a microwave energ…
