Local moment fluctuations in an optimally-doped high Tc superconductor
D. Reznik, J. -P. Ismer, I. Eremin +5
We present results of neutron scattering experiments on YBa2Cu3O6.95 (Tc=93K). Our results indicate that magnetic collective modes due to correlated local moments are present both…
Spin Gap in Optimally-doped YBCO
D. Reznik, L. Pintschovius, Y. Endoh +4
Spin gap in optimally-doped YBCO was investigated by inelastic neutron scattering. We found that q-integrated spectral weight in the vicinity of the spin gap has a shape of a step…
Softening of Cu-O bond stretching phonon in tetragonal HgBaCuO
H. Uchiyama, A. Q. R. Baron, S. Tsutsui +5
Phonons in nearly optimally doped HgBaCuO were studied by inelastic X-ray scattering. The dispersion of the low energy modes is well described by a shell model, while t…
Phonon role in superconductivity of La(2-x)Sr(x)CuO(4) studied by inelastic x-ray scattering
Tatsuo Fukuda, Jun'ichiro Mizuki, Kazuhiko Ikeuchi +6
This paper has been withdrawn by the authors, because we had probably observed some spurious intensity with x=0.29 sample (Fig.3(b)). This came out after further studies of the det…
Oxygen Phonon Branches in Detwinned YBa2Cu3O7
D. Reznik, L. Pintschovius, W. Reichardt +6
We report results of inelastic neutron scattering measurements of phonon dispersions on a detwinned sample of YBaCu3O7 and compare them with model calculations. Plane oxygen bond s…
Anisotropy in the electronic screening of oxygen lattice modes in YBa(2)Cu(3)O(6.95)
R. J. McQueeney, T. Egami, J. -H. Chung +7
Inelastic neutron scattering data from a twinned single-crystal of YBa2Cu3O6.95 are presented that show a distinct a-b plane anisotropy in the oxygen vibrations. The Cu-O bond-stre…
