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 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…

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…

Tin telluride: a weakly co-elastic metal

E. K. H. Salje, D. J. Safarik, K. A. Modic +13

We report resonant ultrasound spectroscopy (RUS), dilatometry/magnetostriction, magnetotransport, magnetization, specific heat, and Sn Mössbauer spectroscopy measurements o…
