高Tc超导体及相关化合物探索研究新进展

RECENT DEVELOPMENT IN THE SEARCH OF HIGHTc SUPERCONDUCTORS AND RELATED COMPOUNDS

所有已知的层状铜氧化合物超导体结构均可按连接单元、分隔单元和三种不同的铜氧平面进行分类，由这几种基本的结构单元也可组合设计出新的结构类型，通过进一步的实验研究可以获得新结构类型的层状铜氧化合物超导体。以这一思想为出发点，本文从材料设计的角度总结了近五年来在新结构层状铜氧化合物超导体探索中的新进展。

All the structures of known layered cuprate superconductors can be classified into connecting layer, separating layer and three kinds of copperoxygen planes. From those basic structural units, it is possible to regenerate the known structures and to design new structure types of layered cuprates. New superconductors thus may be found in preparing the samples with the hypothetical structures. According to this structure architecture point of view, recent development in the search of new highTc superconductors and related compounds is briefly reviewed.
