Description

Detailed measurements of the V-I curves for a number of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} and Bi{sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub 10}/Ag composite tapes were made at 4.2, 27, and 64-77 K as a function of applied magnetic field as well as the angle between the tape face and the direction of applied field. Results suggest that the weak vortex-pinning strength, and the amount of the weakly coupled grain boundaries and of the non-superconducting volume are primary limiting factors for critical current densities in Bi(2212)/Ag and Bi(2223)/Ag, respectively. Furthermore, in both cases, the dissipative voltages arise from the interior of ... continued below
