Nanoscaled magnon transistor based on stimulated three-magnon splitting
Xu Ge, Roman Verba, Philipp Pirro +2
Magnonics is a rapidly growing field, attracting much attention for its potential applications in data transport and processing. Many individual magnonic devices have been proposed…
Controlling selection rules for magnon scattering in nanomagnets by spatial symmetry breaking
Arezoo Etesamirad, Julia Kharlan, Rodolfo Rodriguez +2
Nanomagnets are the building blocks of many existing and emergent spintronic technologies. Magnetization dynamics of nanomagnets is often dominated by nonlinear processes, which ha…
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…
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).…
Spin transport-induced damping of coherent THz spin dynamics in iron
L. Brandt, R. Verba, N. Liebing +6
We study the damping of perpendicular standing spin-waves (PSSWs) in ultrathin Fe films at frequencies up to 2.4 THz. The PSSWs are excited by optically generated ultrashort spin c…
