This project is an investigation of the dynamics of flux-flow in high-Tc superconducting materials which are of technological and fundamental interest. Several methods will be employed to study the behavior of flux-flow. The primary method is the use of a SQUID magnetometer to measure directly the flux-line movement, which signals the onset of flux-flow. By studying the behavior of flux-flow, information about pinning centers and the static structure of the flux lattice can be obtained. In addition, the characteristics of flux-flow noise, important for device applications, will be investigated.

本项目是对高温超导材料中流体流动动力学的研究，具有重要的技术和基础意义。将采用几种方法来研究流体流动的行为。主要方法是使用SQUID磁力计直接测量通量线运动，这标志着通量流的开始。通过对磁通流动行为的研究，可以得到钉钉中心和磁通晶格的静态结构信息。此外，还将研究对器件应用具有重要意义的磁通流噪声的特性。
