Abstract
The fluctuation contribution to the magnetoconductivity for a c axis o riented thin film of YBa2Cu3O7-delta has been studied in magnetic fiel ds up to 12 T and temperatures up to 160 K. The Aronov-Hikami-Larkin ( AHL) theory was unable to describe all of the data. For B perpendicula r to c the theory overestimates the magnetoconductivity at temperature s above epsilon = (T-T-c)/T-c approximate to 0.1.
