Charge disproportionation and site-selective local magnetic moments in the post-perovskite-type FeO under ultra-high pressures
I. Leonov, G. Kh. Rozenberg, I. A. Abrikosov
The archetypal Mott insulator hematite, FeO, is one of the basic oxide components playing an important role in mineralogy of Earth's lower mantle. Its high pressure-te…
Interplay between structural and magnetic-electronic responses of FeAlO to a megabar: site inversion and spin crossover
W. M. Xu, G. R. Hearne, S. Layek +4
X-ray diffraction pressure studies at room temperature demonstrate that the spinel FeAlO transforms to a tetragonal phase at ~18 GPa. This tetragonal phase has a highly…
Site-specific spin crossover in FeTiO post-spinel under high pressures to near a megabar
W. M. Xu, G. R. Hearne, S. Layek +5
X-ray diffraction studies to ~90 GPa at room temperature show that FeTiO ferrous inverse spinel undergoes the following sequence of structural transitions : cubic (Fd3m…
Pressure-driven collapse of the relativistic electronic ground state in a honeycomb iridate
J. P. Clancy, H. Gretarsson, J. A. Sears +16
The electronic ground state in many iridate materials is described by a complex wave-function in which spin and orbital angular momenta are entangled due to relativistic spin-orbit…
Pressure induced spin crossover in disordered α-LiFeO2
Samar Layek, Eran Greenberg, Weiming Xu +4
Structural, magnetic and electrical-transport properties of α-LiFeO2, crystallizing in the rock salt structure with random distribution of Li and Fe ions, have been studied by sync…
Superconductor-insulator transition in fcc-GeSb2Te4 at elevated pressures
Bar Hen, Samar Layek, Moshe Goldstein +8
We show that polycrystalline GeSb2Te4 in the fcc phase (f-GST), which is an insulator at low temperature at ambient pressure, becomes a superconductor at elevated pressures. Our st…
