Well defined grain boundary weak-links in Tl-1223 silver-sheathed tape conductors
We have made detailed current-voltage (I-V) studies of a Tl-1223/Ag tape. Although the tape has a fairly high self-field critical current density J(c) at 77 K (similar to 5 x 10(7) A/m(2)), the I-V characteristics display the "weak-link" signatures well-known for YBa2Cu3O7: linear dissipat...
