## Abstract Dispersion of the real Ξ΅β²(Ξ½) and the imaginary Ξ΅β³(Ξ½) parts of the dielectric function was measured by means of cascaded coherent Stokes Raman scattering (CSRS), in the spectral region of phonon polaritons 520β560 cm^β1^, for single crystals of LiNbO~3~:Mg, before and after chemical redu
The present study is mainly concerned with the relation between electron concentration and anomalous dip appearing on the [110]TA 1 phonon branch of the b 1 -phase (B2-structure) in Ni-Al alloys. By substituting Co for Ni, the dip-position shifts toward the Brillouin zone center. In addition, we pro
