本研究旨在了解高温超导体(HTSC)中的钉扎、耗散现象和磁稳定性。这项工作包括测量单晶和多晶高温超导的磁滞响应、磁弛豫和磁不可逆线。磁特性将与引起钉扎的微结构特征相关联。磁不稳定性(磁通跳跃)将在大型高质量单晶中进行研究。

This research is aimed at understanding pinning, dissipative phenomena and magnetic stability in high temperature superconductors (HTSC's). This work includes measurement of hysteretic response, magnetic relaxation and the magnetic irreversibility line in single crystalline and polycrystalline HTSC's. Magnetic properties will be correlated with microstructural features responsible for pinning. Magnetic instabilities (flux jumps) will be explored in large high quality single crystals.
