Times Cited Count:58 Percentile:86.2(Materials Science, Multidisciplinary)Phonons along the [100] direction, in particular the highest energy Cu-O bond-stretching LO mode, of LaSrCuO have been studied by inelastic X-ray scattering experiments. The LO phonon mode in the = 0.12 sample shows significant softening similar to early neutron studies. We show here a recovery of the softening was found in the = 0.29 sample, where superconductivity degrades and normal metallic conductivity dominates. The results suggest one-to-one correspondence between the softening of this LO phonon and the superconductivity.

Inelastic neutron scattering measurements have been performed on superconducting NaHfNCl powder samples with x=0.27 and 0.38 (T =22 K). We have observed several temperature dependent phonon anomalies, e.g., at E=15, 29, 76, and 81 meV for the former sample. A phonon peak with E=14.5 meV at Q=6 increases for both samples with decreasing temperature below T=40 K, which is much higher than T. The phonon peak is assigned to an ab-plane vibrational mode, E, of chlorine and hafnium atoms, which strongly modifies the electronic band structure. The phonon anomaly is discussed in terms of carrier inhomogeneity.
