Angular Dependence of Critical Current and Grain Alignment in Bi-2223 Superconducting Joint
MDR Open Deposited
We clarify the relationship between the angular dependence of critical current in a Bi-2223 superconducting joint and grain alignment in an intermediate layer of the joint. The angular dependence of critical current for the superconducting joint is discussed using a model to describe that for a Bi-2223 tape. Considering an angle of the c-axis grain misalignment, the angular dependence is calculated. The microstructures of the intermediate layer are observed to evaluate the misalignment angle. The misalignment angle used in calculating the angular dependence is validated. We can conclude that the c-axis grain alignment in the intermediate layer determines the angular dependence of critical current in the superconducting joint.
