摘要: A method for determining simultaneously the inter- and intra-grain critical currents has been developed in welded YBa2Cu3O7 (YBCO) ceramics by solving Inverse Problem local maps of magnetic field remanent state. From that current distribution, density flowing through superconducting weld as well circulating inside grains can be deduced. The is discussed it applied to several examples YBCO/Ag/YBCO welds. results obtained show possible obtain joints with a quality at same level starting material.
