Spin-Hall nano-oscillator with oblique magnetization and Dzyaloshinskii-Moriya interaction as generator of skyrmions and nonreciprocal spin-waves
A. Giordano, R. Verba, R. Zivieri +9
Spin-Hall oscillators are promising sources of spin-wave signals for magnonics applications, and can serve as building blocks for magnonic logic in ultralow power computation devic…
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…
Backscattering immunity of dipole-exchange magnetostatic surface spin waves
M. Mohseni, R. Verba, T. Bracher +4
The existence of backscattering-immune spin-wave modes is demonstrated in magnetic thin films of nano-scale thickness. Our results reveal that chiral Magneto Static Surface Waves (…
Excitation of whispering gallery magnons in a magnetic vortex
K. Schultheiss, R. Verba, F. Wehrmann +10
One of the most fascinating topics in current quantum physics are hybridised systems, in which different quantum resonators are strongly coupled. Prominent examples are circular re…
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…
A magnonic directional coupler for integrated magnonic half-adders
Q. Wang, M. Kewenig, M. Schneider +14
Magnons, the quanta of spin waves, could be used to encode information in beyond-Moore computing applications, and magnonic device components, including logic gates, transistors, a…
