Crystal structure and lattice dynamics of AlB2 under pressure and implications for MgB2
I. Loa, K. Kunc, K. Syassen +1
The effect of high pressures to 40 GPa on the crystal structure and lattice dynamics of AlB2 was studied by synchrotron x-ray powder diffraction, Raman spectroscopy, and first-prin…

MgB_2 under pressure: phonon calculations, Raman spectroscopy, and optical reflectance
K. Kunc, I. Loa, K. Syassen +2
The effect of pressure on optical phonon frequencies of MgB has been calculated using the frozen-phonon approach based on a pseudopotential method. Grüneisen parameters of the…
