Abstract

A 340 nm thin c-axis oriented Bi-2212 superconducting film with TC 80 K (self-field) was synthesized using sedimentation deposition. Surface morphology of the sample was taken and rod-like Cu-rich impurity phases were seen on the surface. These naturally occurring aggregates are vortex pinning sites that enhance the critical current density of the sample.  JC  values were computed and were found to be 123.34 MA/mfor 0 T  and 94.88 MA/mfor 1.0 T at 20 K. Sample magnetoresistance were also taken to provide information on the electrical dissipation in the sample due to the applied external magnetic field.
