Determination of the inter- and intra-granular critical currents in superconducting YBa<inf>2</inf>Cu<inf>3</inf>O<inf>7</inf> welds

A method for determining simultaneously the inter- and intra-grain critical currents has been developed in welded YBa2Cu 3O7 (YBCO) ceramics by solving the Inverse Problem for local maps of the magnetic field in the remanent state. From that current distribution, the current density flowing through...
