Pressure tuning the Jahn-Teller transition temperature in NaNiO
Liam A V Nagle-Cocco, Craig L Bull, Sian E Dutton +1
NaNiO is a layered material consisting of alternating layers of NaO and Jahn-Teller-active NiO edge-sharing octahedra. At ambient pressure it undergoes a broad phase tr…
Robust block magnetism in the spin ladder compound BaFeSe under hydrostatic pressure
Shan Wu, Junjie Yin, Thomas Smart +11
The majority of the iron-based superconductors (FeSCs) exhibit a two-dimensional square lattice structure. Recent reports of pressure-induced superconductivity in the spin-ladder s…
Ammonium Fluoride as a Hydrogen-disordering Agent for Ice
Christoph G. Salzmann, Zainab Sharif, Craig L. Bull +3
The removal of residual hydrogen disorder from various phases of ice with acid or base dopants at low temperatures has been a focus of intense research for many decades. As an anti…
Hydrogen-bond-mediated structural variation of metal guanidinium formate hybrid perovskites with unit cell volume
Zhengqiang Yang, Guanqun Cai, Craig L. Bull +4
The hybrid perovskites are coordination frameworks with the same topology as the inorganic perovskites, but with properties driven by different chemistry, including host-framework…
Pressure-induced collapse of spin-orbital Mott state in the hyperhoneycomb iridate -LiIrO
T. Takayama, A. Krajewska, A. S. Gibbs +8
Hyperhoneycomb iridate -LiIrO is a three-dimensional analogue of two-dimensional honeycomb iridates, such as -LiIrO, which recently appeared as another playgr…
