摘要：

We report on systematic field-cooled magnetization experiments in an Y(0.98)Ca(0.02)Ba(2)Cu(3)O(7-delta) single crystal and melt-textured YBa(2)Cu(3)O(7-delta) samples. Magnetic fields up to 50 kOe 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. (C) 2010 Elsevier B.V. All rights reserved.
