Abstract

Ag-sheathed Bi2212 monocore tapes with core thickness between 80 and 700 μm were heat-treated in flowing O2 in magnetic fields up to 15 T. A uniform high-degree of texture is achieved throughout the thickness of the tapes when heat-treated in a magnetic field (Ha) whereas a large portion of nontextured region exists without magnetic field. The critical current density Jc of the tapes increases with increasing Ha due to enhancement in texture. The self field critical Ic > 1000 A was achieved for tapes with a core thickness of 180 μm. However, for tapes with larger core thicknesses, Ic decreases due to inhomogeneous melting. The magnetic field is more effective in enhancing texture in the early stages of crystal growth.
