Temperature-Dependence of Critical Currents in Superconducting Bi-2212/Ag Wires
The temperature dependence of the critical current density has been studied in magnetic fields up to 12 T for Bi-2212/Ag round wires. In short specimens critical current densities of more than 10000 A/cm(2) have been achieved at 20 K and B = 8 T. In the ca ...

1994Non-universal behaviour of paraconductivity in YBa2Cu3O7-δ films
The authors analysis of in-plane paraconductivity measurements on YBa2Cu3O7-δ (YBCO) films indicates that short-wavelength cutoff effects are significant even very close to the critical point because of the short coherence length ξ. Consequently, the Aslam ...
1993Percolative behavior of the superconductive transition of YBa2Cu3O7 films
The superconductive transition of c-axis-oriented YBa2Cu3O7 thin films, as characterized by measurements of the temperature dependence of the magnetic penetration depth, is found to occur below the Ginzburg-Landau mean-field transition. The divergence of t ...
