Abstract

BSCCO high-temperature superconductors (HTSC) are commercially available in powdered form. Thus, a need to characterize a granular BSCCO (Bi-2201 + Bi-2212) is necessary. When type II superconductors are in a region of applied magnetic fields, vortices are created and these vortices will flow. This will result to an increase in resistivity in the superconductors. The resistivity due to the application of magnetic field is called flux flow resistivity. The presence of Bi-2201 will serve as vortex pinning sites to decrease flux flow resistivity.
The purpose of this paper is to determine the temperature range where pinning is most efficient at varying magnetic fields. This would give us the conditions where the magnetoresistance of the material is least, which is of vital importance especially in the field of HTSC transmission lines.
