Abstract

We report transport and magnetic measurements of critical current densities in single crystals of high T_c superconductors in the Bi-Sr-Ca-Cu-O system. Transport measurements of J_c 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 J_c 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 J_c at temperatures above ∼20 K.
