HIGH CRITICAL-CURRENT DENSITIES IN (TL0.5PB0.5)SR2CA2CU3O9 WITH TC UP TO 115-K

Abstract:

A high critical-current density was observed in the material (Tl 0.5Pb0.5)Sr2Ca2Cu3O 9. Based on magnetic-hysteresis measurements, this single (insulating) Tl-O layer material has a Jc value of 1.24×10 5 A/cm2 when measured at a temperature of 77 K and a field of 1 T. This value of Jc is comparable to that measured here for YBa2Cu3O7 (1.04×105 A/cm 2), having single-conducting Cu-O chains, but considerably greater than the value for the material Tl2Ba2Ca 2Cu3O10 with double (insulating) Tl-O ...
