Estudos de avalanches de vórtices em filmes supercondutores de Nb e MgB2
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 28/10/2008)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 ... -
Flux avalanches in patterned superconducting thin films: ac susceptibility, morphology and related studies
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 12/04/2013)Avalanches are sudden dramatic phenomena that occur in nature. The technique of magneto-optical imaging (MOI) has allowed us to observe abrupt flux entrances in superconductors, the so-called ux avalanches, due to ...
