Abstract
We analyzed magnetization data from a YBa2Cu3O7−δ sample with a sharp transition at Tc = 92.3 K. Two models are discussed and compared. The XY model in three dimensions and the Ginzburg–Landau description based in the lowest Landau level approximation. We confirm the validity of the XY model scaling on low applied magnetic fields. For high applied magnetic fields the scaling behavior of both models provides similar results.
