论文摘要
超导性和磁性是物质的拮抗态。因此，超导状态内的自发磁场的存在是一种有趣的现象，促使广泛的实验和理论研究。在这篇综述中，我们讨论了非常规超导体的最新实验发现，这些发现会自发地打破时间反转对称性和理解其性质的理论努力。我们讨论了主要的实验探针，并对理论方法进行了广泛的说明，以了解顺序参数对称性和相应的配对机制，包括多个频段的重要性。
Superconductivity and magnetism are antagonistic states of matter. The presence of spontaneous magnetic fields inside the superconducting state is, therefore, an intriguing phenomenon prompting extensive experimental and theoretical research. In this review, we discuss recent experimental discoveries of unconventional superconductors which spontaneously break time-reversal symmetry and theoretical efforts in understanding their properties. We discuss the main experimental probes and give an extensive account of theoretical approaches to understand the order parameter symmetries and the corresponding pairing mechanisms including the importance of multiple bands.
