Transport and magnetisation measurements of Tl-1223 tapes - The nature of current paths and the role of grain boundaries at high magnetic fields

Abstract:

The key factors that make the thallium-based 1223 phase conductors attractive candidates for high field applications are a high transition temperature (similar to 115 K), and an irreversibility line comparable to YBa2Cu3O7, However, a third important factor is the grain boundary behaviour. We have made detailed transport current-voltage (I-V) and magnetic studies of a Ag-0.1%Hf sheathed Tl-1223 tape. For low fields (B < 100 mT) its critical current density J(c) performance displays the ''w...
