A New Method to Determine the Coupling Strength of the Interfaces in Seeded-Melt Textured YBa2Cu3Ox
A novel method in determining the coupling strength of the interfaces in seeded melt textured YBa2Cu3Cx has been established. Instead of measuring the transport critical current density across a boundary where many technical problems could occur, this new approach employs the magnetization measurements on a sample that contains a single interface. The coupling strength of any interfaces can be determined by comparing with a standard obtained from a sample without the interface. Some preliminary data are presented on determining the coupling strength of the domain boundaries in seeded-melt textured YBa2Cu3Cx(123).
