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…
