Some effects of the doping alpha-Al2O3 nanoparticles in the transport properties of Bi1.65Pb0.35Sr2Ca2Cu3Oy ceramic superconductors Abstract: We present a preliminary study on the effects of nano-size alpha-Al2O3 (40 nm) in the transport properties of Bi1.65Pb0.35Sr2Ca2Cu3Oy ((Bi, […]
Voltage relaxation and Abrikosov-Josephson vortices in Bi-2223 superconductors doped with alpha-Al2O3 nanoparticles Abstract: We have observed a change in the behaviour of voltage-relaxation curves with remnant magnetic flux, when the maximum magnetic field applied before starting […]
Microstructural and electrical transport properties of uniaxially pressed ceramic superconductors Abstract: We have studied the effect of the pelletization pressure on microstructural and electrical transport properties of superconducting ceramics with starting composition given by the formula […]
