The field-cooled (FC) magnetization M is measured as a function of the applied external field, Ha, for various bulk, Nd-based 123 superconductors which exhibit different magnetization-field characteristics (i.e. with and without secondary peak effect). We find that the FC magnetization data reproduce directly the M(Ha) behaviour measured after zero-field cooling. Based on the critical state model, we derive expressions for the field-cooled magnetization, and show that a large M(0) is essential to achieve large trapped fields in superconducting permanent magnets.
