Pressure tuning of intrinsic and extrinsic sources to the anomalous Hall effect in CrGeTe

Gili Scharf, Daniel Guterding, Bar Hen +7

The integrated Berry curvature is a geometric property that has dramatic implications for material properties. This study investigates the integrated Berry curvature and other cont…

Silvanite AuAgTe: a rare case of gold superconducting material

Yehezkel Amiel, Gyanu P. Kafle, Evgenia V. Komleva +13

Gold is one of the most inert metals, forming very few compounds, some with rather interesting properties, and only two of them currently known to be superconducting under certain…

Superconductor-insulator transitions in three-dimensional indium-oxide at high pressures

Bar Hen, Victor Shelukhin, Eran Greenberg +3

Experiments investigating magnetic-field-tuned superconductor-insulator transition (HSIT) mostly focus on two-dimensional material systems where the transition and its proximate gr…

Phase transitions and spin-state of iron in FeO at the conditions of Earth's deep interior

E. Greenberg, R. Nazarov, A. Landa +8

Iron-bearing oxides undergo a series of pressure-induced electronic, spin and structural transitions that can cause seismic anomalies and dynamic instabilities in Earth's mantle an…

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…

Theoretical and experimental evidence of a site-selective Mott transition in Fe2O3 under pressure

E. Greenberg, I. Leonov, S. Layek +6

We provide experimental and theoretical evidence for a novel type of pressure-induced insulator-metal transition characterized by site-selective delocalization of the electrons. Mö…

Superconductivity in multiple phases of compressed GeSb2Te4

E. Greenberg, B. Hen, Samar Layek +10

Here we report the discovery of superconductivity in multiple phases of the compressed GeSb2Te4 (GST) phase change memory alloy, which has attracted considerable attention for the…
