Ultra-fast vortex motion in dirty Nb-C superconductor with a close-to-perfect edge barrier
O. V. Dobrovolskiy, D. Yu. Vodolazov, F. Porrati +5
The ultra-fast dynamics of superconducting vortices harbors rich physics generic to nonequilibrium collective systems. The phenomenon of flux-flow instability (FFI), however, preve…
Local flux-flow instability in superconducting films near Tc
A. I. Bezuglyj, V. A. Shklovskij, R. V. Vovk +3
Larkin and Ovchinnikov established that the viscous flow of magnetic flux quanta in current-biased superconductor films placed in a perpendicular magnetic field can lose stability…
Supersonic dynamics of guided magnetic flux quanta
O. V. Dobrovolskiy, V. M. Bevz, E. Begun +3
The dynamics of Abrikosov vortices in superconductors is usually limited to vortex velocities km/s above which samples abruptly transit into the normal state. In the Lar…
Reduction of microwave loss by mobile fluxons in grooved Nb films
O. V. Dobrovolskiy, R. Sachser, V. M. Bevz +6
In the mixed state of type II superconductors penetrated by an external magnetic field in the form of a lattice of Abrikosov vortices the dc resistance is known to increase with in…
Microwave emission from superconducting vortices in Mo/Si superlattices
O. V. Dobrovolskiy, V. M. Bevz, M. Yu. Mikhailov +6
Most of superconductors in a magnetic field are penetrated by a lattice of quantized flux vortices. In the presence of a transport current causing the vortices to cross sample edge…
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…
