✦ Synopsis

Singl~high-T c phase .Bi-Pb-Sr-Ca-Cu-O superconductor thin films were prepared on (100) MgO by laser ablatIOn method. Usmg these films we evaluated the coherence lengths from the fluctuation conductivity ~bove T e . These coherence lengths agreed with the ones derived from the highest threshold criterion III H c2 (T) versus T. We also proposed a modified mechanism of the magneto resistivity below T c by which the anomalous Tand H-dependences are well understandable. '

We report measurements of the excess conductivity above Tc for superconducting thin films of single phase (Bio.8Pbo.2)2Sr2Ca2Cu3OlO+y. The experimental excess conductivity was determined from both the normal metal and the Anderson-Zou fits to the normal state resistivity. By using the Aslamazov-Lark
