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…
Instability in domain wall dynamics in almost compensated ferrimagnets
R. V. Ovcharov, B. A. Ivanov, E. G. Galkina +2
Nanoscale self-localized topological spin textures, such as domain walls and skyrmions, are of interest for the fundamental physics of magnets and spintronics applications. Ferrima…
A numerical model for time-multiplexed Ising machines based on delay-line oscillators
Roman V. Ovcharov, Victor H. González, Artem Litvinenko +2
Ising machines (IM) have recently been proposed as unconventional hardware-based computation accelerators for solving NP-hard problems. In this work, we present a model for a time-…
Non-Reciprocal Spin Pumping in Asymmetric Magnetic Trilayers
Yevgen Pogoryelov, Manuel Pereiro, Somnath Jana +9
In magnetic trilayer systems, spin pumping is generally addressed as a reciprocal mechanism characterized by one unique spin mixing conductance common to both interfaces. However,…
Spatial Mapping of Torques within a Spin Hall Nano-oscillator
Timothy M Spicer, Paul S Keatley, Thomas H J Loughran +8
Time-resolved scanning Kerr microscopy (TRSKM) was used to study precessional magnetization dynamics induced by a radio frequency (RF) current within a AlO/Py(5 nm)/Pt(6 nm…
