Ultra-long-living magnons in the quantum limit
Rostyslav O. Serha, Kaitlin H. McAllister, Fabian Majcen +8
Solid-state platforms based on bosonic quasiparticles offer a compelling route toward on-chip quantum information technologies scalable to nanometer dimensions. Coherence time, a k…
Experimental observation of Josephson oscillations in a room-temperature Bose-Einstein magnon condensate
Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova, Pascal Frey +5
The alternating current (ac) Josephson effect in a time-independent spatially-inhomogeneous setting is manifested by the occurrence of Josephson oscillations - periodic macroscopic…
Bottleneck accumulation of hybrid magneto-elastic bosons
Dmytro A. Bozhko, Peter Clausen, Gennadii A. Melkov +6
It is known that an ensemble of magnons, quanta of spin waves, can be prepared as a Bose gas of weakly interacting quasiparticles with conservation of the particle number. Furtherm…
On supercurrents in Bose-Einstein magnon condensates in YIG ferrimagnet
Dmytro A. Bozhko, Alexander A. Serga, Peter Clausen +4
Recently E. Sonin commented [1] on our preprint "Supercurrent in a room temperature Bose-Einstein magnon condensate" [2,3], arguing that our "claim of detection of spin supercurren…
Detection of spin waves in permalloy using planar Hall effect
Yuri V. Kobljanskyj, Gennadii A. Melkov, Alexander A. Serga +2
Rectification of microwave oscillations of magnetization in a permalloy film is realized using planar Hall effect. Two different rectified signals are obtained: a signal from the l…
Supercurrent in a room temperature Bose-Einstein magnon condensate
D. A. Bozhko, A. A. Serga, P. Clausen +6
We report evidence for the existence of a supercurrent of magnons in a magnon Bose-Einstein condensate prepared in a room temperature yttrium-iron-garnet magnetic film and subject…
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…
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…
