Vortex counting and velocimetry for slitted superconducting thin strips
V. M. Bevz, M. Yu. Mikhailov, B. Budinská +7
The maximal speed for magnetic flux quanta is determined by the energy relaxation of unpaired electrons and is thus essential for superconducting microstrip single-photon…
Vortex jets generated by edge defects in current-carrying superconductor thin strips
A. I. Bezuglyj, V. A. Shklovskij, B. Budinska +6
At sufficiently large transport currents , a defect at the edge of a superconducting strip acts as a gate for the vortices entering into it. These vortices form a je…
Moving flux quanta cool superconductors by a microwave breath
O. V. Dobrovolskiy, C. Gonzalez-Ruano, A. Lara +7
Almost any use of a superconductor implies a nonequilibrium state. Remarkably, the non-equilibrium states induced by a microwave stimulus and the dynamics of magnetic flux quanta (…
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…
Upper frequency limits for vortex guiding and ratchet effects
O. V. Dobrovolskiy, E. Begun, V. M. Bevz +2
Guided and rectified motion of magnetic flux quanta are important effects governing the magneto-resistive response of nanostructured superconductors. While at low ac frequencies th…
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…
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…
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…
