Abstract: We report first principles calculations of the structural parameters and phonon dispersion of the tetragonal noncentrosymmetric heavy fermion compound ${\mathrm{CeAuAl}}_{3}$. Taking into account weak magnetoelastic interactions of the rare-earth (RE) ions with the spectrum of… read more here.

Abstract: Raman spectra of Ho1−xNdxFe(BO3)4 (x=1, 0.75, 0.5, 0.25) have been studied in temperature range 10–400K. Two compositions (x=1, x=0.75) demonstrate structural phase transition with soft mode restor... read more here.
