摘要:

我们基于当前文献,简要概述了铜氧化物高温超导体中一类配对态对称性的若干结果。介绍了利用现代激光ARPES方法或c轴扭转约瑟夫森结对空穴掺杂Bi-2212体系进行近节点d型能隙函数的高精度测量结果。讨论了最近支持电子掺杂铜氧化物NdCeCuO具有d型配对对称性且具有特殊非单调函数形式的实验证据。描述了一项新的重要结果,即通过相位敏感测试在电子掺杂无限层SrLaCuO体系中识别出母体高温超导结构的超导序参量具有dx^2-y^2对称性。所呈现的一组数据表明,d波配对对称性,特别是dx^2-y^2形式,对铜氧化物体系中的高温导电性起着至关重要的作用。

英文摘要:

We report a brief overview ofa number of results on a type of pairing state symmetry in cuprates HTSC from a current literature. The results of recent high-precision measurements of near-nodal d-type gap functions by a modern laser-based ARPES method or by a c-axis twisted Josephson junction for hole-doped Bi-2212 system are presented. Recent experimental evidence in favor of d-type pairing symmetry, with a special nonmonotonic functional form, for electron-doped cuprate NdCeCuO is discussed. A new essential results on the identification of dx^2-y^2 symmetry of superconducting order parameter for parent high-Tc cuprate structure, electron-doped infinite layer SrLaCuO system, by the phase sensitive tests is described. A complex of the data presented indicates a vital role of d-wave pairing symmetry, in the special dx^2-y^2 form for high-temperature conductivity in cuprate systems.
