Anisotropy of transport properties normal and parallel to the tape plane in Bi-2223/Ag tapes

The c-axis conduction characteristics of silver-clad Bi-2223 and Bi-2212 tapes were investigated. Specifically, transport, resistivity and critical current measurements were carried out under varying temperatures and magnetic fields. The measurements, which looked at the superconducting current path parallel and perpendicular to the tape plane, revealed that the critical currents flowing along and normal to the tape plane have similar field orientation and magnetic field dependences.
