摘要

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.
