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…
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-…
Emission of fast-propagating spin waves by an antiferromagnetic domain wall driven by spin current
Roman V. Ovcharov, B. A. Ivanov, Johan Åkerman +1
Antiferromagnets (AFMs) have great benefits for spintronic applications such as high frequencies (up to THz), high speeds (up to tens of km/s) of magnetic excitations, and field-fr…
