: A High-Valent Insulating Palladate
Qingqing Yang, Ning Guo, Tieyan Chang +10
A high-valent palladate, , has been synthesized for the first time. Single crystals with dimensions of 20 m on edge were successfully grown using the flux method…
Damage of bilayer structure in La3Ni2O7-d induced by high pO2 annealing
Yulin Zhang, Cuiying Pei, Ning Guo +12
The discovery of superconductivity with onset temperature of ~80 K in pressurized bilayer Ruddlesden-Popper La3Ni2O7-d has attracted much attention. Despite intense research, deter…
Pyrochlore NaYbO2: A potential Quantum Spin Liquid Candidate
Chuanyan Fan, Tieyan Chang, Longlong Fan +14
The search for quantum spin liquids (QSL) and chemical doping in such materials to explore superconductivity have continuously attracted intense interest. Here, we report the disco…
Signature of superconductivity in pressurized La4Ni3O10-x single crystals grown at ambient pressure
Feiyu Li, Yinqiao Hao, Ning Guo +4
Nickelates have attracted enormous attention since the discovery of high-temperature superconductivity in La3Ni2O7 under high pressure. However, whether superconducting nickelate s…
Bulk Crystal Growth and Single-Crystal-to-Single-Crystal Phase Transitions in the Averievite CsClCu5V2O10
Chao Liu, Chao Ma, Tieyan Chang +7
Quasi-two-dimensional averievites with triangle-kagome-triangle trilayers are of interest due to their rich structural and magnetic transitions and strong spin frustration that are…
