Superconducting Properties in Arrays of Nanostructured β-Gallium
(Nature Publishing Group, 2017-11-10)
Samples of nanostructured β-Ga wires were synthesized by a novel method of metallic-flux nanonucleation. Several superconducting properties were observed, revealing the stabilization of a weak-coupling type-II-like ...
From the nonlinear Fokker-Planck equation to the Vlasov description and back: Confined interacting particles with drag
(American Physical Society, 2018-02)
Nonlinear Fokker-Planck equations endowed with power-law diffusion terms have proven to be valuable tools for the study of diverse complex systems in physics, biology, and other fields. The nonlinearity appearing in these ...
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 ...
Transição ordem-desordem da matéria de vórtices em supercondutores detectada através do terceiro harmônico da suscetibilidade AC
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2008-12-01)
Although a vortex state, in type II superconductors, has been anticipated more than 50 years ago, a great deal of theoretical and experimental efforts has still been done in an attempt to investigate how the dynamics of ...
Estudio estructural, químico y morfológico de películas base-Bi crecidas por deposito químico a partir de Trifenilbismuto, Pb(TMHD)2, Sr(TMHD)2, Ca(TMHD)2 y Cu(TMHD)2. (TMHD: 2,2,6,6-tetrametil-3,5-heptanedionato)
(2012-03-06)
Este trabajo tuvo como objetivo principal el estudio estructural, químico y morfológico de películas base-Bi crecidas por depósito químico a partir de trifenil-Bi y Bis(2,2,6,6-tetrametil-3,5-heptanedionato) de: Pb, Sr, ...
Bridge in micron-sized Bi2Sr2CaCu2O8+y sample act as converging lens for vortices
(Elsevier Science, 2021-11-15)
We report on direct imaging of vortex matter nucleated in micron-sized Bi2Sr2CaCu2O8+y superconducting samples that incidentally present a bridge structure. We find that when nucleating vortices in a field-cooling condition ...
