We report on measurements of both the longitudinal and transverse magnetoresistivity (MR) of oxygen-reduced YBa2Cu3O7-δ(YBCO) thin films with critical temperatures betweenTc=55 K andTc=89 . We find the MR solely caused by the suppression of superconducting fluctuations by a magnetic field. In fully oxygenated samples both the Aslamazov–Larkin process (AL) and another, presumably the Maki–Thompson process (MT), contribute to the MR. In oxygen-deficient samples the MT process unambiguously is absent, thus indicating an unconventional (non-s-wave) pairing symmetry in YBCO. |
