Outline of Final Research Achievements

We investigated effects of Mg impurity doping on Bi2Sr2CaCu2Oy high-temperature superconductor (Bi-2212 HTS). We used Bi-2212 HTS whisker as a sample and tried to improve its anisotropy of critical current density (Jc). For the Mg-doping, we adopted thermal diffusion process. In the process, non-superconducting phase is expected to appear on the surface of the whisker. From experimental results, we found that the anisotropy parameter of Jc can be improved from 13.8 to 1.89 by doping Mg impurity with 400 °C annealing.
