Interação da matéria de vórtices com estruturas de defeitos : detecção das primeiras penetrações
(Universidade Federal de São Carlos, 2009-08-07)
This thesis results from a systematic study of the interactions between penetrated vortices and pinning centers carried out on structured superconductors films of YBCO, Nb and Pb. A regular array of pinning centers (antidots, ...
Interação da matéria de vórtices com estruturas de defeitos em filmes de Nb
(Universidade Federal de São Carlos, 2009-03-30)
In this work we have studied the Vortex Matter dynamics in Nb superconducting films with different arrays of columnar defects. For that we studied the order-disorder line H (T) OD , where the melting of the vortex lattice ...
