Signature of Superconductivity in Pressurized Trilayer-nickelate Pr${}_4$Ni${}_3$O${}_{10-\delta }$

Abstract

The discovery of high-temperature superconductivity in La${}_3$Ni${}_2$O${}_7$ and La${}_4$Ni${}_3$O${}_{10}$ under pressure has drawn extensive attention. Herein, we report systematic investigations on the evolutions of structure, magnetism, and electrical resistance of Pr${}_4$Ni${}_3$O${}_{10-\delta }$ polycrystalline samples under various pressures. Pr${}_4$Ni${}_3$O${}_{10-\delta }$ exhibits density wave transitions on Ni and Pr sublattices at about 158 K and 4.3 K, respectively, and the density wave can be progressively suppressed by pressure. A structural transformation from the monoclinic $P{2}_1/a$ space group to the tetragonal $I4/mmm$ occurs at around 20 GPa. An apparent drop in resistance with evident magnetic field dependence is observed as pressure above 20 GPa, indicating the emergence of superconductivity in Pr${}_4$Ni${}_3$O${}_{10-\delta }$ polycrystalline samples. The discovery of the signature of superconductivity in Pr${}_4$Ni${}_3$O${}_{10-\delta }$ broadens the family of nickelate superconductors and provides a new platform for investigating the mechanisms of superconductivity in the Ruddlesden-Popper phases of nickelates.
