Kurzfassung:
The local and transport critical current densities in a melt-processed Y-Ba-Cu-O were estimated by analyzing the results of the Campbell method and DC magnetization measurement in terms of the Campbell model in which the reversible fluxoid motion is treated. The factor of overestimation of the local current density was evaluated from the slope of minor DC magnetization curve. The obtained local critical current density was about one order of magnitude larger than the transport critical current density and was comparable to a theoretical value where normal particles of the 211 phase are assumed to act as dominant pinning centers.
