Estudos de avalanches de vórtices em filmes supercondutores de Nb e MgB2
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2008-10-28)
If a type-II superconductor is cooled down in a zero applied field and subsequently an external field, larger than the first critical field, is applied, vortices enter through the sample borders until they are captured by ...
Vortex creep and critical current densities Jc in a 2 um thick SmBa2Cu3O7-δ coated conductor with mixed pinning centers grown by co-evaporation
(IOP Publishing, 2016-06-03)
We report the critical current densities Jc and flux creep rates in a 2 mm thick SmBa2Cu3O7-dcoated conductor produced by co-evaporation. The sample presents strong pinning produced by correlated disorder (boundaries between ...
Vortex dynamics differences due to twin-boundary pinning anisotropy in YBa2Cu3Ox at low temperatures for H parallel to ab planes

Thermally activated flux creep in nanocrystalline δ-MoN thin films
(Pergamon-Elsevier Science Ltd, 2018-11)
We study the vortex dynamics in a nanocrystalline 420 nm thick δ-MoN film on Si (100). The film was grown at room temperature by reactive sputtering and following it is crystallized by thermal annealing at 973 K for one ...
Disorder, critical currents, and vortex pinning energies in isovalently substituted BaFe2(As1_xPx)2
(American Physical Society, 2013-03)
We present a comprehensive overview of vortex pinning in single crystals of the isovalently substituted iron-based superconductor BaFe2(As1−xPx)2, a material that qualifies as an archetypical clean superconductor, containing ...
Microfluidic manipulation of magnetic flux domains in type-I superconductors: Droplet formation, fusion and fission
(Nature Publishing Group, 2017-12-21)
The magnetic flux domains in the intermediate state of type-I superconductors are known to resemble fluid droplets, and their dynamics in applied electric current is often cartooned as a "dripping faucet". Here we show, ...
Pinning-Dependent Field-Driven Domain Wall Dynamics and Thermal Scaling in an Ultrathin Pt / Co / Pt Magnetic Film
(American Physical Society, 2014-07)
Magnetic-field-driven domain wall motion in an ultrathin Pt / Co ( 0.45 nm ) / Pt ferromagnetic film with perpendicular anisotropy is studied over a wide temperature range. Three different pinning dependent dynamical ...
Commensurability effects in magnetic properties of superconducting Nb thin films with periodic submicrometric pores
(Elsevier Science, 2009-12)
Pinning properties in 100 nm thick continuous and porous superconducting Nb films are examined by ac susceptibility and dc magnetization measurements. The Nb film was deposited on a smooth Si substrate, while the porous ...
Behavior of the flux-flow resistivity in mesoscopic superconductors
