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…

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…
