New measurements of the transition to the normal state induced by high current densities in high-Tc superconductor microbridges under thermal smallness conditions
J. M. Doval, J. Maza, C. Torron +3
We address here the superconductivity quenching under an external magnetic field of amplitudes up to 1 T and in the so-called "thermal smallness" condition, when the microbridge wi…
An analytical approach to the thermal instability of superconducting films under high current densities
Jesús Maza, Gonzalo Ferro, Manuel Rodríguez Osorio +2
Using the Green's function of the 3D heat equation, we develop an analytical account of the thermal behaviour of superconducting films subjected to electrical currents larger than…
Size effects on the quenching to the normal state in YBa2Cu3O7-delta thin film superconductors
Mauricio Ruibal, Gonzalo Ferro, Manuel R. Osorio +3
To probe the quenching mechanisms under high current densities, current-voltage curves have been measured in YBa2Cu3O7-delta thin film microbridges with widths lower than the therm…
On the interplay between Tc-inhomogeneities at long length scales and thermal fluctuations around the average superconducting transition in cuprates
F. Vidal, J. A. Veira, J. Maza +2
We review some aspects of the interplay between inhomogeneities at long length scales and the intrinsic fluctuations of Cooper pairs above Tc in HTSC. These inhomogeneities do not…
Normal-superconducting transition induced by high current densities in YBa2Cu3O7-d melt-textured samples and thin films: Similarities and differences
M. T. Gonzalez, J. Vina, S. R. Curras +3
Current-voltage characteristics of top seeded melt-textured YBa2Cu3O7-d are presented. The samples were cut out of centimetric monoliths. Films characteristics were also measured o…
