Higher critical current density achieved in Bi-2223 High-Tc superconductors
Get PDFAbstractBi2Sr2Ca2Cu3Ox (Bi-2223) were prepared using a solid state reaction method at different sintering times and temperatures. Structural phase identifications have been done using X-Ray analysis and refinement by Reitveld method which proves the coexistence of Bi-2223 and Bi-2212 phases. The critical transition temperature Tc and critical current density Jc values were measured using superconducting quantum interference device magnetometer (SQUID) and by the magneto-optics technique. A remarkable rapid decrease to the diamagnetic signal in the magnetization versus temperature M(T) at 110Â K and Jc around 1.2Â ĂÂ 107 A/m2 at 5Â K are confirmed for the Bi-2223 compound
