Magnetic microstructure and flux dynamics of high-T/sub c/ superconductors
- 1. ATandT Bell Laboratories, Holmdel, New Jersey 07733
Description
We present high-resolution Bitter patterns which reveal the magnetic microstructure of the high-T/sub c/ superconductor Ba2YCu3O7, allowing the direct observation of vortices, and their response to magnetic-field changes. By forming patterns in the presence of a time-varying magnetic field, or a transport current, we also study the dynamics of flux motion. Our results reveal a hierarchy of pinning sites and a remarkable anisotropy in the characteristics of neighboring twins, and allow the mapping of superconducting regions in the presence of circulating and transport currents
