Abstract

Nd-Ba-Cu-O sample fabricated by the oxygen-controlled-melt-growth method exhibits large J_c values in a high field region and also shows a secondary peak effect. In the present study, the Nd-Ba-Cu-O sample was characterized by using the flux profile technique, in which the χ′ signal is plotted against the amplitude of AC field. J_c values determined with the flux profile technique also showed a clear secondary peak effect. In addition, such J_c values were higher than those measured with DC susceptibility, presumably due to a difference in the electric field to determine J_c.
