Spin-wave phase inverter upon a single nanodefect

O. V. Dobrovolskiy, R. Sachser, S. A. Bunyaev +9

Local modification of magnetic properties of nanoelements is a key to design future-generation magnonic devices, in which information is carried and processed via spin waves. One o…

Radiofrequency generation by coherently moving fluxons

Oleksandr V. Dobrovolskiy, Roland Sachser, Michael Huth +4

A lattice of Abrikosov vortices in type II superconductors is characterized by a periodic modulation of the magnetic induction perpendicular to the applied magnetic field. For a co…

Non-dissipative drag of superflow in a two-component Bose gas

D. V. Fil, S. I. Shevchenko

A microscopic theory of a non-dissipative drag in a two-component superfluid Bose gas is developed. The expression for the drag current in the system with the components of differe…

Surface pinning in amorphous ZrTiCuNiBe alloy

V. D. Fil, D. V. Fil, Yu. A. Avramenko +2

We have measured the amplitude and the phase of an electromagnetic (EM) field radiated from superconductor (amorphous ZrTiCuNiBe alloy) in the mixed state due to interaction of the…
