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…

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…
