Effect of Ag-doping on Texture Development of Bi2212 Bulks in High Magnetic Field

Pure and Ag-doped Bi2212 bulks were prepared by melt processing in 9T magnetic field. It is found that an obvious texture has been developed in the Ag-doped bulks; while in the pure Bi2212 bulks no texture can be observed. Further analysis shows that the texture development in Bi2212 bulks is highly sensitive to the maximum temperature in the melt processing. Ag-doping leads to a homogeneous melting at a lower temperature and the texture can thus be obtained in the Ag-doped bulks.
