7. 高温超伝導体の微細組織と臨界電流密度

抄録

Critical current density of the superconductor is not an intrinsic property, but it is strongly dependent on the microstructure. Hence, microstructural control is very important in order to achieve large critical currents. In this review, I will present several defects which are considered to be responsible for flux pinning enhancement in oxide superconductors.
