Pressure-dependent "Insulator-Metal-Insulator" Behavior in Sr-doped LaNiO
Mingyu Xu, Shuyuan Huyan, Haozhe Wang +7
Recently, superconductivity at high temperatures has been observed in bulk LaNiO under high pressure. However, the attainment of high-purity LaNiO s…
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…
Long-Range Structural Order in a Hidden Phase of Ruddlesden-Popper Bilayer Nickelate LaNiO
Haozhe Wang, Long Chen, Aya Rutherford +2
The recent discovery of superconductivity in Ruddlesden-Popper bilayer nickelate, specifically LaNiO, has generated significant interest in the exploration of high-temp…
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…
Strong enhancement of magnetic ordering temperature and structural/valence transitions in EuPd3S4 under high pressure
S. Huyan, D. H. Ryan, T. J. Slade +11
We present a comprehensive study of the mixed valent compound, EuPd3S4, by electrical transport, X-ray diffraction, time-domain 151Eu synchrotron Mössbauer spectroscopy, and X-ray…
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…
Continuous spin excitations in the three-dimensional frustrated magnet K2Ni2(SO4)3
Weiliang Yao, Qing Huang, Tao Xie +12
Continuous spin excitations are widely recognized as one of the hallmarks of novel spin states in quantum magnets, such as quantum spin liquids (QSLs). Here, we report the observat…
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…
Non-centrosymmetric SrIrO obtained under High Pressure
Haozhe Wang, Madalynn Marshall, Zhen Wang +5
SrIrO with strong spin-orbit coupling (SOC) and Hubbard repulsion (U) hosts Mott insulating states. The similar crystal structure, magnetic and electronic properties, p…
