Abstract

Nickelate superconductors have attracted a great deal of attention over the past few decades due to their similar crystal and electronic structures with high-temperature cuprate superconductors. Here, we report superconductivity in a pressurized Ruddlesden-Popper phase single crystal La4Ni3O10(n=3) and its interplay with the density wave order in the phase diagram. With increasing pressure, the density wave order, as indicated by the anomaly in the resistivity, is progressively suppressed, followed by the emergence of superconductivity around 25 K under the I4/mmm space group. The susceptibility measurements confirm bulk superconductivity with a volume fraction exceeding 80%. Moreover, theoretical analysis unveils that antiferromagnetic superexchange interactions can serve as the effective pairing interaction for the emergence of superconductivity in pressurized La4Ni3O10. Our research provides a new platform for the investigation of the unconventional superconductivity mechanism in Ruddlesden-Popper trilayer perovskite nickelates.

压力下三层La4Ni3O10镍酸盐的超导性

镍酸盐超导体由于具有与高温铜超导体相似的晶体和电子结构，在过去的几十年中引起了人们的广泛关注。本文报道了高压Ruddlesden-Popper相单晶La4Ni3O10（n=3）的超导性及其与相图中密度波序的相互作用。随着压力的增加，电阻率异常所反映的密度波序逐渐被抑制，随后在I4/mmm空间群下出现25 K左右的超导性。磁化率测量证实了体积分数超过80%的块体超导性。此外，理论分析表明，反铁磁超交换相互作用可以作为加压La4Ni3O10中超导性产生的有效配对相互作用。本研究为研究Ruddlesden-Popper三层钙钛矿镍酸盐的非常规超导机制提供了一个新的平台。2025年由美国物理学会出版
