Mutual synchronization of two asymmetric-nano-constriction-based spin-Hall nano-oscillators
Roman V. Ovcharov, Roman S. Khymyn, Akash Kumar +1
We propose an asymmetric-nanoconstriction (ANC) design of spin-Hall nano-oscillators (SHNOs) and investigate mutual synchronization of a pair of such devices using micromagnetic si…
Ultra-large mutually synchronized networks of 10 nm spin Hall nano-oscillators
Nilamani Behera, Avinash Kumar Chaurasiya, Akash Kumar +5
While mutually interacting spin Hall nano-oscillators (SHNOs) hold great promise for wireless communication, neural networks, neuromorphic computing, and Ising machines, the highes…
A frequency tunable low-noise YIG-GGG based oscillator with strong magneto-elastic coupling
Paolo Sgarro, Roman Ovcharov, Roman Khymyn +4
We present a frequency tunable magneto-acoustic oscillator (MAO) operating in low-phase-noise and complex dynamical regimes based on a single composite YIG-GGG resonator. The magne…
Analytical modelling for the frequency behavior of two distinct modes in nano-constriction spin Hall nano-oscillator
H. Ghanatian, M. Rajabali, R. Khymyn +5
Nano-constriction spin-Hall nano-oscillators (NC-SHNOs) have garnered considerable interest due to their potential use as efficient and adjustable nano-sized sources of microwave s…
A spinwave Ising machine
Artem Litvinenko, Roman Khymyn, Victor H. González +4
We demonstrate a spin-wave-based time-multiplexed Ising Machine (SWIM), implemented using a 5 m thick Yttrium Iron Garnet (YIG) film and off-the-shelf microwave components. The…
A tunable magneto-acoustic oscillator with low phase noise
A. Litvinenko, R. Khymyn, V. Tyberkevych +3
A frequency-tunable low phase noise magneto-acoustic resonator is developed on the base of a parallel-plate straight-edge bilayer consisting of a yttrium-iron garnet (YIG) layer gr…
