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…
