1. Obtenção e caracterização de supercondutores de Bi2212 texturizados com introdução de centros artificiais de aprisionamento / Production and characterization of textured Bi2212 superconductors with introduction of artificial pinning centers.
The present work analyzed the texturing conditions of Ag/Bi2212 samples (Bi2Sr2CaCu2O8+δ) in the form of bulks and of tapes, verifying the influence of heat treatment, atmosphere, silver addition and addition of zirconia or calcium zirconate. The additions of zirconia or calcium zirconate, with particles of submicron or nanometric (below 200nm) dimensio

2. ConfiguraÃÃo, anisotropia e defeitos em uma rede de vÃrtices na presenÃa de nanoarmadilhas
Since Abrikosov s work in 1957, it. has been clear the vortex lattice existence and stability in specific magnetic fields and temperature values of type ll super- conductors. On external currents and Thermic fluctuations, vortices move through the superconductor salable resulting thermal dissipation. But it is salvage to most. actual technologic applications
