Adiabatic Control of Spin-Wave Propagation using Magnetisation Gradients
Marc Vogel, Rick Aßmann, Philipp Pirro +3
Spin waves are of large interest as data carriers for future logic devices. However, due to the strong anisotropic dispersion relation of dipolar spin-waves in in-plane magnetised…
Magnonic crystal based forced dominant wavenumber selection in a spin-wave active ring
A. D. Karenowska, A. V. Chumak, A. A. Serga +2
Spontaneous excitation of the dominant mode in a spin-wave active ring -- a self-exciting positive-feedback system incorporating a spin-wave transmission structure -- occurs at a c…
Non-resonant wave front reversal of spin waves used for microwave signal processing
V. I. Vasyuchka, G. A. Melkov, A. N. Slavin +3
It is demonstrated that non-resonant wave front reversal (WFR) of spin-wave pulses caused by pulsed parametric pumping can be effectively used for microwave signal processing. When…
Reverse Doppler effect in backward spin waves scattered on acoustic waves
A. V. Chumak, P. Dhagat, A. Jander +2
We report on the observation of reverse Doppler effect in backward spin waves reflected off of surface acoustic waves. The spin waves are excited in a yttrium iron garnet (YIG) fil…
Current-controlled dynamic magnonic crystal
A. V. Chumak, T. Neumann, A. A. Serga +2
We demonstrate a current-controlled, dynamic magnonic crystal. It consists of a ferrite film whose internal magnetic field exhibits a periodic, cosine-like variation. The field mod…
Scattering of surface and volume spin waves in a magnonic crystal
A. V. Chumak, A. A. Serga, S. Wolff +2
The operational characteristics of a magnonic crystal, which was fabricated as an array of shallow grooves etched on a surface of a magnetic film, were compared for magnetostatic s…
Generation of pulse trains by current-controlled magnetic mirrors
A. A. Serga, T. Neumann, A. V. Chumak +1
The evolution of a spin-wave packet trapped between two direct current-carrying wires placed on the surface of a ferrite film is observed by Brillouin light scattering. The wires a…
Design and optimization of one-dimensional ferrite-film based magnonic crystals
A. V. Chumak, A. A. Serga, S. Wolff +2
One-dimensional magnonic crystals have been implemented as gratings of shallow grooves chemically etched into the surface of yttrium-iron garnet films. Scattering of backward volum…
Bose-Einstein condensation of magnons under incoherent pumping
A. V. Chumak, G. A. Melkov, V. E. Demidov +3
Bose-Einstein condensation in a gas of magnons pumped by an incoherent pumping source is experimentally studied at room temperature. We demonstrate that the condensation can be ach…
Parametrically-stimulated recovery of a microwave signal using standing spin-wave modes of a magnetic film
A. V. Chumak, A. A. Serga, G. A. Melkov +3
The phenomenon of storage and parametrically-stimulated recovery of a microwave signal in a ferrite film has been studied both experimentally and theoretically. The microwave signa…
