Time-resolved observation of magnon splitting into vortex gyration and Floquet spin waves
T. Devolder, R. Lopes Seeger, C. Heins +9
Forced excitations at frequencies in the range of the first order azimuthal spin waves of a magnetic disk in the vortex state are known to scatter into the vortex gyration mode, th…

Excitation of vortex core gyration in nanopillars through driven Floquet magnons
Gauthier Philippe, Joo-Von Kim
The dynamics of vortex states in confined geometries like thin-film disks are characterized by a sub-GHz gyration, representing the damped oscillatory motion of the vortex core abo…

Unidirectional spin wave emission by travelling pair of magnetic field profiles
Gauthier Philippe, Mathieu Moalic, Jarosław W. Kłos
We demonstrate that the spin wave Cherenkov effect can be used to design the unidirectional spin wave emitter with tunable frequency and switchable direction of emission. In our nu…
