Abstract
We report on systematic field-cooled magnetization experiments in an Y0.98Ca0.02Ba2Cu3O7−δ single crystal and melt-textured YBa2Cu3O7−δ samples. Magnetic fields up to 50kOe were applied and a paramagnetic response related to the superconducting state was observed. We discuss our results in terms of the flux compression scenario into the sample.
