Abstract
Measurements of the fundamental ac-susceptibility provide a sensitive tool to study the shielding behavior of ceramic high-T(c) superconduct ing material. In this work, ac-susceptibility data for differently pre pared YBaCuO-samples are presented. From the data, information can be extracted about an effective grain size, which is not necessarily iden tical to the optically determined particle size. It is demonstrated th at the data allow an estimation of the bulk quality which depends stro ngly on the preparation conditions.
