Pressure-Induced Phase Transitions in Bilayer LaNiO
Mingyu Xu, Greeshma C. Jose, Aya Rutherford +6
LaNiO exists in two polymorphs: an unconventional structure with alternating layers of single- and triple-layered nickel-oxygen octahedra, and a classical double-layere…
Tetragonal BaCoO: A Co Ferromagnetic Mott Insulator with Inverted Spin Crossover
Mingyu Xu, Haozhe Wang, Krishna Prasad Koirala +13
The interplay between crystal electric field splitting of d states and Hund's rule exchange energy in cobalt-based perovskites offers a promising avenue for inducing spin-state tra…
Pseudosymmetry in Tetragonal Perovskite SrIrO Synthesized under High Pressure
Haozhe Wang, Alberto de la Torre, Joseph T. Race +6
In this study, we report a tetragonal perovskite structure of SrIrO (P4/mmm, a = 3.9362(9) Å, c = 7.880(3) Å) synthesized at 6 GPa and 1400 C, employing the ambient pressure…
Impersonating a Superconductor: High-Pressure BaCoO, an Insulating Ferromagnet
Haozhe Wang, Xianghan Xu, Danrui Ni +4
We report the high-pressure synthesis (6 GPa, 1200 C) and ambient pressure characterization of hexagonal HP-BaCoO. The material (with the 2H crystal structure) has a…
Incommensurate Spiral Spin Order in CaMnBi observed via High Pressure Neutron Diffraction
Madalynn Marshall, Haozhe Wang, Antonio M. dos Santos +2
High pressure neutron diffraction is employed to investigate the magnetic behavior of CaMnBi in extreme conditions. In contrast to antiferromagnetic ordering on Mn atoms re…
Is La3Ni2O6.5 a Bulk Superconducting Nickelate?
Ran Gao, Lun Jin, Shuyuan Huyan +7
Superconducting states onsetting at moderately high temperatures have been observed in epitaxially-stabilized RENiO2-based thin films. However, recently it has also been reported t…
The Pressure-Stabilized Polymorph of Indium Triiodide
Danrui Ni, Haozhe Wang, Xianghan Xu +2
A layered rhombohedral polymorph of indium (III) triiodide is synthesized at high pressure and temperature. The unit cell symmetry and approximate dimensions are determined by sing…
Erbium-excess gallium garnets
Chen Yang, Haozhe Wang, Lun Jin +5
A series of garnets of formula Er3+xGa5-xO12 is described, for which we report the crystal structures for both polycrystalline and single-crystal samples. The x limit in the garnet…
Hidden Hydroxides in KOH-Grown BaNiO3 Crystals: A Potential Link to Their Catalytic Behavior
Lun Jin, Haozhe Wang, Xianghan Xu +10
The hexagonal perovskite BaNiO3, prepared via non-ceramic approaches, is known to act as a good catalyst for the oxygen-evolution reaction (OER) in alkaline media. Here we report o…
Synthesis and physical properties of a new layered ferromagnet, Cr1.21Te2
Zhixue Shu, Haozhe Wang, Na Hyun Jo +5
Single crystals of a new layered compound, Cr1.21Te2, was synthesized via a vapor transport method. The crystal structure and physical properties were characterized by single cryst…
