Raman Scattering of Metals to Very High Pressures
Alexander F. Goncharov, Eugene Gregoryanz, Viktor V. Struzhkin +4
We review recent development in Raman techniques and diamond anvil cell technology, that allow measurements of Raman of metals in the megabar pressure range. The Raman technique in…
New Phases of Solid Nitrogen
Eugene Gregoryanz, Alexander Goncharov, Russell J. Hemley +3
We report the discovery of a new class of molecular phases of solid nitrogen at high pressures and temperatures by Raman and infrared spectroscopy and powder x-ray diffraction. Unl…
Spectroscopic Studies of the Vibrational and Electronic Properties of Solid Hydrogen to 285 GPa
Alexander F. Goncharov, Eugene Gregoryanz, Russell J. Hemley +1
We report Raman scattering and visible to near-infrared absorption spectra of solid hydrogen under static pressure up to 285 GPa at 85-140 K. We obtain pressure dependences of vibr…
Superconductivity in the Chalcogens up to Multimegabar Pressures
Eugene Gregoryanz, Viktor V. Struzhkin, Russell J. Hemley +3
Highly sensitive magnetic susceptibility techniques were used to measure the superconducting transition temperatures in S up to 231(5) GPa. S transforms to a superconductor wi…
Phonon-assisted electronic topological transition in MgB2 under pressure
V. V. Struzhkin, A. F. Goncharov, R. J. Hemley +4
We report measurements of the superconducting critical temperature Tc of polycrystalline MgB2 samples containing isotopically pure (10)B and (11)B under quasi-hydrostatic pressure…
Nuclear Inelastic X-Ray Scattering of FeO to 48 GPa
Viktor V. Struzhkin, Ho-kwang Mao, Jingzhu Hu +8
The partial density of vibrational states has been measured for Fe in compressed FeO (wüstite) using nuclear resonant inelastic x-ray scattering. Substantial changes have been obse…
