Granularity is one of the main features restricting the maximum current which a superconductor can carry without losses, persisting as an important research topic when applications are concerned. To directly observe its effects on a typical thin supe

Resposta magneto-elétrica de nanofitas supercondutoras granulares : simulações utilizando o formalismo de Ginzburg-Landau dependente do tempo

Autor: Presotto, Adriana Guirao.

Orientador: Rafael Zadorosny
Correntes de transporte interagem com os vórtices de Abrikosov nos supercondutores do tipo II via força de Lorentz (FL), o que pode resultar em seu movimento. Esse movimento ocorrerá se FL suprimir a força de pin

We investigate the effect of the divalent Ca atoms at the trivalent Y site of YBa2Cu3O7−δ on the magnetoconductivity and magnetic irreversibility of single crystals and a polycrystalline sample. The magnetic irreversibility displays the de Almeida
