โœฆ Synopsis

Unusual forms of resistive superconducting transition have been observed in some n-type cuprate ceramics. Their shape are strongly magnetic field dependent. In some cases, the transition shows a double peak behavior : the resistivity presenting two maxima before reaching zero. This behavior and its change with magnetic field has been explained by an interplay between the superconducting transition of the grains and the Josephson temperature of the intergranular region.

We present a model based on a self consistent medium approach which describes the various behaviors one can observe in these ceramics.

Critical current density and its history effect in Bi-based high T c superconducting tapes were measured using an a.c. inductive method with various magnetic fields and temperatures. A rapid decrease in the critical current density with increasing temperature and the history effect were observed in
