An insulating YBa 2 Cu 3 O 7Àd (YBCO) thin film was grown by inverted cylindrical magnetron (ICM) sputtering and under nitrogen cooling instead of oxygen in situ annealing. This insulating film went through different annealing processes in flowing oxygen, each time with increasing annealing temperat
In order to test the stability of the observed fluctuation regimes, low magnetic fields were applied perpendicular to the Cu-O 2 atomic planes. When the transition is approached from above we first observe a three-dimensional (3D) Gaussian regime then a crossover to a genuine critical region where t
