Spatially resolved quantum magnetometry and stray-field reconstruction of permalloy microdisks using boron-vacancy centers in hexagonal boron nitride
Peiting Wen, Shuyu Wen, Jiang Qu +13
Transferable hexagonal boron nitride (hBN) hosting negatively charged boron-vacancy (VB) spin defects offers a versatile platform for integrated quantum magnetometry, yet qua…
Benchmarking a magnon-scattering reservoir with modal and temporal multiplexing
Christopher Heins, Joo-Von Kim, Lukas Körber +3
Physical reservoir computing has emerged as a powerful framework for exploiting the inherent nonlinear dynamics of physical systems to perform computational tasks. Recently, we pre…
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…
Nontrivial Aharonov-Bohm effect and alternating dispersion of magnons in cone-state ferromagnetic rings
Vera Uzunova, Lukas Körber, Agapi Kavvadia +4
Soft magnetic dots in the form of thin rings have unique topological properties. They can be in a vortex state with no vortex core. Here, we study the magnon modes of such systems…
Control of 4-magnon-scattering in a magnonic waveguide by pure spin current
Toni Hache, Lukas Koerber, Tobias Hula +6
We use a pure spin current originating from the spin Hall effect to generate a spin-orbit torque (SOT) strongly reducing the effective damping in an adjacent ferromagnet. Due to ad…
