Abstract
The magnetic susceptibility of YBaCuO and BiSrCaCuO bulk samples are discussed in terms of intra- and intergranular flux-pinning processes. A fit based on Clem's model (Physica C 153-155 (1988) 50) is proposed which allows a comparison of the quality of a large variety of superconducting compounds with different morphologies (bulk, thin films and single crystals)Keywords
