A New Superconductor Parent Compound NaMn6Bi5 with Quasi-One-Dimensional Structure and Lower Antiferromagnetic-Like Transition Temperatures
文献摘要：
Mn-based superconductors are very rare and their superconductivity has only been reported in three-dimensional MnP and quasi-one-dimensional KMn6Bi5 and RbMn6Bi5 with[Mn6Bi5]-columns under high pressures.Here we report the synthesis,magnetism,electrical resistivity,and specific heat capacity of the newly discovered quasi-one-dimensional NaMn6Bi5.Compared with other AMn6Bi5(A=K,Rb,and Cs),NaMn6Bi5 has abnormal Bi-Bi bond lengths and two antiferromagnetic-like transitions at 47.3 K and 51.8 K.Anisotropic resistivity and low-temperature non-Fermi liquid behavior are observed.Heat capacity measurement reveals that the Sommerfeld coefficient for NaMn6Bi5 is unusually large.Using first-principles calculations,an unusual enhancement of density of states near the Fermi level is demonstrated for NaMn6Bi5.The features make NaMn6Bi5 a more suitable platform to explore the interplay of magnetism and superconductivity.
