Collective vortex rectification effects in films with a periodic pinning array
Clecio C. de Souza Silva, J. Van de Vondel, B. Y. Zhu +2
The vortex ratchet effect has been studied in Al films patterned with square arrays of submicron antidots. We have investigated the transport properties of two sets of samples: (i)…
Masking effect of heat dissipation on the current-voltage characteristics of a mesoscopic superconducting square with leads
D. Y. Vodolazov, F. M. Peeters, M. Morelle +1
A theoretical analysis based on a numerical solution of the coupled time-dependent Ginzburg-Landau and heat dissipation equations shows a strong dependence of the critical currents…
Vortex rectification effects in films with periodic asymmetric pinning
J. Van de Vondel, C. C. de Souza Silva, B. Y. Zhu +2
We study the transport of vortices excited by an ac current in an Al film with an array of nanoengineered asymmetric antidots. The vortex response to the ac current is investigated…
Nucleation of superconductivity in a mesoscopic loop of varying width
M. Morelle, D. S. Golubovic, V. V. Moshchalkov
We study the evolution of the superconducting state in a perforated disk by varying the size of the hole. The superconducting properties are investigated by means of transport meas…
Influence of the sample geometry on the vortex matter in superconducting microstructures
M. Morelle, J. Bekaert, V. V. Moshchalkov
The dependence of the vortex penetration and expulsion on the geometry of mesoscopic superconductors is reported. Hall magnetometry measurements were performed on a superconducting…
Magnetic phase shifter for superconducting qubit
D. S. Golubovic, W. V. Pogosov, M. Morelle +1
We have designed and investigated a contactless magnetic phase shifter for flux-based superconducting qubits. The phase shifter is realized by placing a perpendicularly magnetized…
