Pressure-enhanced superconductivity and its correlation with suppressed resistance dip in (La,Pr)3Ni2O7 films
Jinyu Zhao, Guangdi Zhou, Shu Cai +11
The discovery of superconductivity with a transition temperature (Tc) exceeding 40 K in La3Ni2O7 and (La,Pr)3Ni2O7 thin films at ambient pressure provides a viable platform for the…
T-linear specific heat in pressurized and magnetized Shastry-Sutherland Mott insulator SrCu2(BO3)2
Jing Guo, Pengyu Wang, Cheng Huang +13
The pressurized Shastry-Sutherland Mott insulator SrCu2(BO3)2 has been found to host a plaquette-singlet phase and an antiferromagnetic phase that break different symmetries sponta…
Signatures of a Lifshitz transition in pressurized electron-doped cuprate
Jinyu Zhao, Shu Cai, Zhaoyu Liu +14
It is well known that the electronic structure of hole-doped cuprate superconductors is tunable through both chemical doping and external pressure, which frequently offer us new in…
Superconducting susceptibility signal captured in a record wide pressure range
Shu Cai, Jinyu Zhao, Di Peng +11
In recent years, the resistance signature of the high temperature superconductivity above 250 K in highly compressed hydrides (more than 100 GPa) has garnered significant attention…
Investigations of key issues on the reproducibility of high-Tc superconductivity emerging from compressed La3Ni2O7
Yazhou Zhou, Jing Guo, Shu Cai +11
Recently, the signatures of superconductivity near 80 K have been discovered in the single crystal of La3Ni2O7 under pressure, which makes it a new candidate of the high-temperatur…
Superconducting-insulating phase transition in pressurized Ba1-xKxBiO3
Jinyu Han, Xiangde Zhu, Jianfeng Zhang +15
We report the first observation of a pressure-induced transition from a superconducting (SC) to an insulating (I) phase in single-crystal Ba1-xKxBiO3 (x = 0.4, 0.43, 0.52, and 0.58…
