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…

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…

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…
