Simultaneous multitone microwave emission by DC-driven spintronic nano-element
A. Hamadeh, D. Slobodianiuk, R. Moukhader +9
Current-induced self-sustained magnetization oscillations in spin-torque nano-oscillators (STNOs) are promising candidates for ultra-agile microwave sources or detectors. While usu…
Deeply nonlinear excitation of self-normalised exchange spin waves
Qi Wang, Roman Verba, Björn Heinz +9
Spin waves are ideal candidates for wave-based computing, but the construction of magnetic circuits is blocked by a lack of an efficient mechanism to excite long-running exchange s…
Curvilinear spin-wave dynamics beyond the thin-shell approximation: Magnetic nanotubes as a case study
Lukas Körber, Roman Verba, Jorge A. Otálora +4
Surface curvature of magnetic systems can lead to many static and dynamic effects which are not present in flat systems of the same material. These emergent magnetochiral effects c…
Antiferromagnetic parametric resonance driven by voltage-controlled magnetic anisotropy
Riccardo Tomasello, Roman Verba, Victor Lopez-Dominguez +5
Voltage controlled magnetic anisotropy (VCMA) is a low-energy alternative to manipulate the ferromagnetic state, which has been recently considered also in antiferromagnets (AFMs).…
Parametric Excitation and Instabilities of Spin Waves driven by Surface Acoustic Waves
Moritz Geilen, Roman Verba, Alexandra Nicoloiu +10
The parametric excitation of spin waves by coherent surface acoustic waves is demonstrated experimentally in metallic magnetic thin film structures. The involved magnon modes are a…
