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…
Unconventional spin currents in magnetic films
Dmytro A. Bozhko, Halyna Yu. Musiienko-Shmarova, Vasyl S. Tiberkevich +4
A spin current - a flow of spin angular momentum - can be carried either by spin polarised free electrons or by magnons, the quanta of a moving collective oscillation of localised…
Tunable space-time crystal in room-temperature magnetodielectrics
Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova, Dmytro A. Bozhko +5
We report the experimental realization of a space-time crystal with tunable periodicity in time and space in the magnon Bose-Einstein Condensate (BEC), formed in a room-temperature…
Long-distance supercurrent transport in a room-temperature Bose-Einstein magnon condensate
Dmytro A. Bozhko, Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova +4
The term supercurrent relates to a macroscopic dissipation-free collective motion of a quantum condensate and is commonly associated with such famous low-temperature phenomena as s…
From Kinetic Instability to Bose-Einstein Condensation and Magnon Supercurrents
Alexander J. E. Kreil, Dmytro A. Bozhko, Halyna Yu. Musiienko-Shmarova +4
Evolution of an overpopulated gas of magnons to a Bose-Einstein condensate and excitation of a magnon supercurrent, propelled by a phase gradient in the condensate wave function, c…
Spin Seebeck effect and ballistic transport of quasi-acoustic magnons in room-temperature yttrium iron garnet films
Timo Noack, Halyna Yu. Musiienko-Shmarova, Thomas Langner +9
We studied the transient behavior of the spin current generated by the longitudinal spin Seebeck effect (LSSE) in a set of platinum-coated yttrium iron garnet (YIG) films of differ…
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…
Bose-Einstein Condensation of Quasi-Particles by Rapid Cooling
M. Schneider, T. Brächer, D. Breitbach +18
The fundamental phenomenon of Bose-Einstein Condensation (BEC) has been observed in different systems of real and quasi-particles. The condensation of real particles is achieved th…
