Abstract A strongly pinned (TI/Pb)-(Sr/Ba)-CaCuO bulk superconductor of TI-(1223) phase with a single TI-O plane has been developed with a magnetic J c over 43 000 A cm −2 at 77 K and about 600 000 A cm −2 at 20 K and 1 T. Single crystals of TI-(1223) have been prepared and used for investigations of magnetization hysteresis anisotropy using SQUID. When the field was applied parallel to the c axis, a high field peak related to inhomogeneous stoichiometry and properties across the specimen was observed in the magnetization hysteresis loop around 1 T at 77 K. Ag-sheathed tapes with TI-(1223) core were fabricated by the drawing-rolling method. The transport J c was 25 000 A cm −2 in the absence of a magnetic field, and stayed - 500 A cm −2 up to 8 T at 77 K.
