Abstract

Comparative studies of certain properties have been performed on Ag-sheathed YBa2Cu3Oy wire and pressed and sintered YBa2Cu3Oy. We found for our samples that the critical current density of the Ag-sheathed sample is more than five times larger than that of the sintered sample, whereas the superconducting volume fraction estimated from magnetic moment measurement is larger for the sintered sample. These contrariant results are discussed in relation to the microstructures of the samples observed by means of SEM images, exploring the way to further improvement of critical current density in the Ag-sheathed YBa2Cu3Oy.
