Local Structure of Substituted High Tc Superconductors

利用X射线吸收精细结构（XAFS）技术， 提出，测量有关取代原子的局部结构 在高温超导体中。 这些实验应该提供 这对理解铜的独特作用有重大帮助， 在这些材料中。 此外，他们还提出了初步的 单晶或取向膜的实验和取代的- 利用同步加速器辐射的高偏振， 增强特定键的XAFS信号幅度 方向

A series of X-ray Absorption Fine Structure (XAFS) experiments is proposed, to measure the local structure about substituted atoms in high-Tc superconductors. Such experiments should furnish significant help in understanding the unique role that copper plays in these materials. In addition, they propose preliminary experiments on single crystal or oriented films and substituted- materials using the high polarization of synchrotron radiation to enhance the amplitude of the XAFS signal for particular bond directions.
