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…
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…
Long-range proximity-induced superconductivity in polycrystalline Co nanowires
M. Kompaniiets, O. V. Dobrovolskiy, C. Neetzel +4
We report an experimental study of proximity effect-induced superconductivity in crystalline Cu and Co nanowires and a nanogranular Co nanowire structure in contact with a supercon…
Vortex lattice symmetry break in nanostructured Nb thin films
Oleksandr V Dobrovolskiy, Evgeniya Begun, Michael Huth +2
An advanced mask-less nanofabrication technique, focused electron beam-induced deposition (FEBID), has been employed on epitaxial Nb thin films for their ferromagnetic decoration b…
