摘要
探索新的高温超导材料与揭示非常规超导机理一直是凝聚态物理研究的重点.除了铜氧化物超导体和铁基超导体这两大家族之外,其他过渡金属基非传统超导材料相对较少,其中锰基超导材料尤其稀少.晶格维度的降低通常会抑制磁有序并增强自旋涨落,可以以此为思路探索新的锰基超导体.近年来,一个新的准一维锰基材料家族AMn_(6)Bi_(5)(A=Na,K,Rb和Cs)被发现.其中,AMn_(6)Bi_(5)(A=K,Rb和Cs)在高压下表现出非常规超导电性,加深了人们对于非常规超导与反铁磁关联的认识.
Exploration of new high-temperature superconducting materials and the revelation of unconventional superconductivity mechanisms have always been the focus of condensed matter physics.Except for the two large families of copper oxide and iron-based superconductors,other transition metal-based unconventional superconductors are relatively rare,and manganese-based superconductors are particularly scarce.Reducing the lattice dimension usually weakens magnetic ordering and enhances spin fluctuation,which can be utilized to explore more manganese-based superconductors.Recently,a new family of quasi-one-dimensional manganese-based materials,AMn_(6)Bi_(5)(A=Na,K,Rb,and Cs),was discovered.AMn_(6)Bi_(5)(A=K,Rb,and Cs)exhibits unconventional superconductivity under high pressure.The discovery of these new quasi-one-dimensional manganese-based superconductors has further elucidated our understanding of the correlation between unconventional superconductivity and antiferromagnetism.
