Abstract

The critical current of (Bi,Pb)2Sr2Ca 2Cu3Ox (Bi-2223) was varied between 2 A and 120 A using three different approaches: field angle with respect to the wide face of the tape, mechanical strain, and heat treatments. The results of transport loss measurements carried out on the three sets of samples showed that reduced critical current density caused an increase in AC loss as expected from Norris's model. Comparison of the data among the three sets, however, showed some interesting features in the dependence of the AC loss behavior on the method used to vary critical current density. The results are explained based on the type of defects, localized or distributed, caused by the particular approach used in lowering the critical current.
