Critical Current Densities in Single-Crystal Bi2.2Sr 2Ca0.8Cu2O8+Δ
We report transport and magnetic measurements of critical current densities in single crystals of high Tc superconductors in the Bi-Sr-Ca-Cu-O system. Transport measurements of Jc were made using a pulse method, while a vibrating sample magnetometer was used to measure M-H loops of oriented crystals in fields up to 15 kOe. Values for transport Jc in zero applied field are higher than those of Ba2YCu3O 7 single crystals at comparable temperatures. Also we observe a strong magnetic field dependence for Jc at temperatures above ∼20 K.
