Abstract

This article presents the temperature and field dependencies of the critical current density for Bi-2212/Ag round wires. The experiments were carried out in magnetic fields up to 12T. Critical current densitites exceeding 10000 A/cm2 have been achieved at 20 K and 8 T for the round wires. At B = 0 J(c) values above 20000 A/cm2 have been reached at a temperature of 50 K. Below 20 K a very small difference of the J(c) values for increasing and decreasing applied fields has been observed. This hysteresis effect suggests that the material contains some weak links.
