摘要

Sr2RuO4 中的超导现象是 30 年前发现的。这种非常规超导体的许多引人入胜之处包括自旋三重超导性，它有可能同时携带电荷和自旋超电流。这一提议曾被考虑了很长时间，但最终在 2019 年被推翻。尽管在过去几年中进行了大量研究，但典型的非常规超导体 Sr2RuO4 的超导对称性问题仍然悬而未决。在此，我们将重点介绍最近的争议，并从一个角度探讨如何达成最终的解决方案。

Thirty years of puzzling superconductivity in Sr2RuO4

Superconductivity in Sr2RuO4 was discovered 30 years ago. Among the many intriguing aspects of this unconventional superconductor is the picture of spin-triplet superconductivity, which could potentially carry both charge and spin supercurrents. This proposal was considered for a long time but was ultimately disproven in 2019. Despite intense research over the past several years, the superconducting symmetry of the archetypal unconventional superconductor Sr2RuO4 remains unresolved. Here we highlight the recent controversies and give a perspective of how the final resolution may be reached. After 30 years of extensive research, the nature of the unconventional superconductivity in Sr2RuO4 is still not fully understood. This Perspective summarizes the controversies surrounding this and discusses future research.
