Anisotropy in the transport properties of type II superconducting films with periodic pinning
(2013-01-01)
Using numerical simulations, we analyze the anisotropy effects in the critical currents and dynamical properties of vortices in a thin superconducting film submitted to hexagonal and Kagomé periodical pinning arrays. The ...

Superconductivity in nanocrystalline tungsten thin films growth by sputtering in a nitrogen-argon mixture
(Elsevier Science SA, 2019-06)
We report on the structural and superconducting properties of nanocrystalline tungsten thin films growth by sputtering at room temperature with an N2:Ar mixture (N2 from 3% to 50%). The crystalline phases were identified ...
Morphology of flux avalanches in patterned superconducting films
(2013-06-01)
It is well known that under certain circumstances, magnetic fields applied perpendicularly to the plane of superconducting films can trigger flux avalanches. In such cases, the penetration has a tree-like profile. However, ...

Imageamento magneto-ótico quantitativo em filmes finos supercondutores bicamada e com gradiente nanométrico de espessura
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-12-11)
Vortex matter in superconductors has been the focus of research of both theoretical and experimental groups around the world.
When developing superconducting devices patterned on thin films one should bear in mind that ...
Critical forces at fractional matching fields in superconducting thin films with triangular pinning lattice
(2017-07-01)
We numerically study the commensurability effects in the critical forces in a type II superconducting thin film with vortices under the influence of a triangular pinning lattice at sub matching fields and zero temperature. ...
Ultra‑fast kinematic vortices in mesoscopic superconductors: the effect of the self‑field
(Nature Research, 2020-10-29)
In the present work, we have studied the crossover between type I and type II superconductivity on mesoscopic superconducting thin films by numerically solving the 3D Ginzburg-Landau equations. We determined the dependence ...
Crossover from type I to type II regime of mesoscopic superconductors of the first group
(IOP, 2019-12-02)
In the present work, we have studied the crossover between type I and type II superconductivity on mesoscopic superconducting thin films by numerically solving the 3D Ginzburg-Landau equations. We determined the dependence ...
