We have compared the magnetic behaviour of two identicaly shaped single crystals, TI2Ba2CaCu208 and Bi2Sr:CaCu20 s. The critical current density is found to decrease more rapidly with temperature in Bi-2212 although it is the highest in this material at low temperatures (T < 10K). I-V characteristic
Bi 2 Sr 2 CaCu 2 O 8+d (Bi-2212) superconducting single crystals were prepared by a modified vertical Bridgman method using large crucibles of a 30 mm external diameter with a cone-shaped bottom. In order to obtain a large single crystal with high crystallinity, we optimized the growth conditions, w
