โœฆ Synopsis


Ihe intergrain critical current densities, J , parallel and perpendicular to c-axis were measured as a function of the magnetic field at 4.2 and 77.3K by an ac inductive method for the fairly oriented Bi 1 6PbO 4Sr2ca2CuPy specimens. 'Ihe J 's perpendicular to c-axis were higher than those parallel" to c-axis, about ten times wfthin 5T at 4.2K, and about three times within O.lT at 77.3K. Our results suggect the orientation of each grain to be especially worthwhile for performing the high J c at the low temperature.

BiPbSrCaCuO silver sheathed high T c superconducting wires were fabricated through the solid reaction process. It is proposed in this paper that the magnetic field dependence of Jc of the wire is dominated by the Lorentz force perpendicular to the c-axis, caused by a transport current with c-axis co
