Tunable artificial vortex ice in nanostructured superconductors with frustrated kagome lattice of paired antidots
C. Xue, J. -Y. Ge, A. He +5
Theoretical proposals for spin ice analogs based on nanostructured superconductors have suggested larger flexibility for probing the effects of fluctuations and disorder than in th…
Magnetic Dipoles at Topological Defects in the Meissner State of a Nanostructured Superconductor
Jun-Yi Ge, Vladimir N. Gladioli, Cun Xue +5
In a magnetic field, superconductivity is manifested by total magnetic field expulsion (Meissner effect) or by the penetration of integer multiples of the flux quantum Φ_0. Here we…
Superconducting properties of corner-shaped Al microstrips
O. -A. Adami, D. Cerbu, D. Cabosart +8
The electrical transport properties of corner-shaped Al superconducting microstrips have been investigated. We demonstrate that the sharp turns lead to asymmetric vortex dynamics,…
Vortex core deformation and stepper motor behavior in a superconducting ratchet
J. Van de Vondel, V. N. Gladilin, A. V. Silhanek +4
We investigated experimentally the frequency dependence of a superconducting vortex ratchet effect by means of electrical transport measurements and modeled it theoretically using…
Mesoscopic cross-film cryotrons: Vortex trapping and dc-Josephson-like oscillations of the critical current
A. Yu. Aladyshkin, G. W. Ataklti, W. Gillijns +8
We investigate theoretically and experimentally the transport properties of a plain Al superconducting strip in the presence of a single straight current-carrying wire, oriented pe…
Tunable anisotropic nonlinearity in superconductors with asymmetric antidot array
A. Yu. Aladyshkin, J. Van de Vondel, C. C. de Souza Silva +1
The influence of the spatial asymmetry of the pinning potential on the spectral composition of the voltage, induced in perforated superconducting Al bridges by the injection of a s…
Self organized mode locking effect in superconductor / ferromagnet hybrids
J. Van de Vondel, A. V. Silhanek, V. Metlushko +3
The vortex dynamics in a low temperature superconductor deposited on top of a rectangular array of micrometer size permalloy triangles is investigated experimentally. The rectangul…
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)…
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…
