Pressure-induced s,p-d electron redistribution accompanies structural transformation in amorphous Zr-Cu alloy under compression
P. Dziegielewski, J. Antonowicz, K. Georgarakis +6
Extreme compression can reorganize atomic valence states, in some regimes driving charge from spatially extended orbitals into more compact ones. We investigate this effect in amor…
Optically detected magnetic resonance of nitrogen-vacancy centers in microdiamonds inside nanopolycrystalline diamond anvil cell
Masahiro Ohkuma, Keigo Arai, Kenji Ohta +4
We demonstrated optically detected magnetic resonance (ODMR) of nitrogen-vacancy (NV) centers in microdiamonds inside a diamond anvil cell pressurized with nanopolycrystalline diam…
Pushing the limits of flow strength in diamond
Anirudh Hari, Kento Katagiri, Wanghui Li +34
Extreme pressures and temperatures create conditions that allow even hard and brittle materials to deform plastically. Despite extensive research, the upper limits of flow strength…
Interplay between local structure and electronic properties on CuO under pressure
V. Cuartero, V. Monteseguro, A. Otero-de-la-Roza +5
The electronic and local structural properties of CuO under pressure have been investigated by means of X-ray absorption spectroscopy (XAS) at Cu K edge and ab-initio calculations,…
Mechanism of pressure induced amorphization of SnI4: a combined X-ray diffraction -- X-ray absorption spectroscopy study
Emiliano Fonda, Alain Polian, Toru Shinmei +2
We have studied the amorphization process of SnI4 up to 26.8GPa with unprecedented experimental details by combining Sn and I K edge X-ray absorption spectroscopy and powder X-ray…
Interplay of the electronic and lattice degrees of freedom in A_{1-x}Fe_{2-y}Se_{2} superconductors under pressure
M. Bendele, C. Marini, B. Joseph +12
The local structure and electronic properties of RbFeSe are investigated by means of site selective polarized x-ray absorption spectroscopy at the iron and sele…
Polycrystalline γ-boron: As hard as polycrystalline cubic boron nitride
Jiaqian Qin, Norimasa Nishiyama, Hiroaki Ohfuji +4
The Vickers hardness of polycrystalline γ-B was measured using a diamond indentation method. The elastic properties of polycrystalline γ-B (B=213.9 GPa, G=227.2 GPa, and E=503.3 GP…
Phase relations in boron at pressure up to 18 GPa and temperature up to 2200 °C
Jiaqian Qin, Tetsuo Irifune, Haruhiko Dekura +4
The phase relations in boron have been investigated at high pressure and high temperature using a multianvil apparatus, and the quenched sample has been analyzed by x-ray diffracti…
