Control of magnon frequency combs in magnetic rings
Christopher Heins, Attila Kákay, Joo-Von Kim +4
Using Brillouin light scattering microscopy, we study the rich dynamics in magnetic disks and rings governed by non-linear interactions, focusing on the role of vortex core dynamic…

Self-induced Floquet magnons in magnetic vortices
Christopher Heins, Lukas Körber, Joo-Von Kim +6
Driving condensed matter systems with periodic electromagnetic fields can result in exotic states not found in equilibrium. Termed Floquet engineering, such periodic driving applie…

Combined frequency and time domain measurements on injection-locked, constriction-based spin Hall nano-oscillators
T. Hache, T. Weinhold, K. Schultheiss +7
We demonstrate a combined frequency and time domain investigation of injection-locked, constriction-based spin Hall nano-oscillators by Brillouin light scattering (BLS) and time-re…
