Abstract
The static magnetic susceptibility of two different YBa2Cu3O6.30 samples shows a peak near to 45 K; the peak shows a dependence on the field and on the magnetic history. This feature has been explained by the combined effect of regions with a Curie-like behavior and superconducting regions. The origin of these regions in the material has been discussed.
