Ag-sheathed Tl-1212 tapes with a nominal composition of (Tl1.2Cr0.15)Sr2CaCu2O7 were fabricated using the powder-in-tube (PIT) method. The tapes (approximately 3-4 cm long) were annealed in oxygen flow at 820 �C, 870 �C and 890 �C each for 30 minutes, 1 hour and 5 hours, respectively. The x-ray diff...
