Coherent excitation of heterosymmetric spin waves with ultrashort wavelengths
G. Dieterle, J. Förster, H. Stoll +16
In the emerging field of magnonics, spin waves are foreseen as signal carriers for future spintronic information processing and communication devices, owing to both the very low po…
X-Ray Microscopy of Spin Wave Focusing using a Fresnel Zone Plate
Joachim Gräfe, Martin Decker, Kahraman Keskinbora +6
Magnonics, i.e. the artificial manipulation of spin waves, is a flourishing field of research with many potential uses in data processing within reach. Apart from the technological…
Spin wave mediated unidirectional Vortex Core Reversal by Two Orthogonal Monopolar Field Pulses: The Essential Role of Three-dimensional Magnetization Dynamics
Matthias Noske, Hermann Stoll, Manfred Fähnle +8
Scanning transmission x-ray microscopy is employed to investigate experimentally the reversal of the magnetic vortex core polarity in cylindrical Ni81Fe19 nanodisks triggered by tw…
Three-dimensional Character of the Magnetization Dynamics in Magnetic Vortex Structures - Hybridization of Flexure Gyromodes with Spin Waves
Matthias Noske, Hermann Stoll, Manfred Fähnle +8
Three-dimensional linear spin-wave eigenmodes of a Permalloy disk having finite thickness are studied by micromagnetic simulations based on the Landau-Lifshitz-Gilbert equation. Th…
Unidirectional sub-100 ps magnetic vortex core reversal
Matthias Noske, Ajay Gangwar, Hermann Stoll +8
The magnetic vortex structure, an important ground state configuration in micron and sub-micron sized ferromagnetic thin film platelets, is characterized by a curling in-plane magn…
Low-amplitude magnetic vortex core reversal by non-linear interference between azimuthal spin waves and the vortex gyromode
Markus Sproll, Matthias Noske, Hans Bauer +7
We demonstrate a non-linear interference due to an active 'dual frequency' excitation of both, the sub-GHz vortex gyromode and multi-GHz magneto-static spin waves in ferromagnetic…
200 ps Vortex Core Reversal by Azimuthal Spin Waves
Matthias Kammerer, Hermann Stoll, Matthias Noske +4
Spin wave mediated vortex core reversal has been investigated by time-resolved scanning transmission X-ray microscopy (STXM). Movies showing the development of the spin wave and vo…
Magnetic Vortex Core Reversal by Excitation of Spin Waves
Matthias Kammerer, Markus Weigand, Michael Curcic +8
Micron-sized magnetic platelets in the flux closed vortex state are characterized by an in-plane curling magnetization and a nanometer-sized perpendicularly magnetized vortex core.…
