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…

Pressure Dependence of the Raman Spectrum, Lattice Parameters and Superconducting Critical Temperature of MgB2
A. F. Goncharov, V. V. Struzhkin, E. Gregoryanz +6
We have observed a strongly broadened Raman band of MgB2 that shows anomalously large pressure dependence of its frequency. This band and its pressure dependence can be interpreted…
