The 'luctuation contribution to the magnetoconductivity for a c axis oriented thin film of YBa2Cu307\_~5 has been studied in magnetic fields up to 12 T and temperatures up to 160 K. The Aronov-Hikami-Larkm (AHL) theory was unable to describe all of the data For B\_l\_c the theory overestimates the m
We report on measurements of both the longitudinal and transverse magnetoresistivity (MR) of oxygen-reduced YBa 2 Cu 3 O 7-Ξ΄ (YBCO) thin films with critical temperatures between T c = 55 K and T c = 89 K. We find the MR solely caused by the suppression of superconducting fluctuations by a magnetic f
