Single-crystal growth of underdoped Bi-2223
S. Adachi, T. Usui, K. Takahashi +10
To investigate the origin of the enhanced Tc ({\approx} 110 K) of the trilayer cuprate superconductor Bi2Sr2Ca2Cu3O10+δ (Bi-2223), its underdoped single crystals are a critical req…
Evidence for a charge collective mode associated with superconductivity in copper oxides from neutron and x-ray scattering measurements of LaSrCuO
S. R. Park, T. Fukuda, A. Hamann +5
In superconducting copper oxides some Cu-O bond-stretching phonons around 70meV show anomalous giant softening and broadening of electronic origin and electronic dispersions have l…
Inelastic neutron scattering study of phonon anomalies in La1.5Sr0.5NiO4
R. Kajimoto, M. Fujita, K. Nakajima +4
The high-energy phonons in La1.5Sr0.5NiO4, in which the checkerboard charge ordering is formed, was investigated by the inelastic neutron scattering. We found that the longitudinal…
Effects of charge inhomogeneities on elementary excitations in La_{2-x}Sr_xCuO_4
S. R. Park, A. Hamann, L. Pintschovius +7
Purely local experimental probes of many copper oxide superconductors show that their electronic states are inhomogeneous in real space. For example, scanning tunneling spectroscop…
Electron-phonon anomaly related to charge stripes: static stripe phase versus optimally-doped superconducting La1.85Sr0.15CuO4
D. Reznik, L. Pintschovius, M. Fujita +3
Inelastic neutron scattering was used to study the Cu-O bond-stretching vibrations in optimally doped La1.85Sr0.15CuO4 (Tc = 35 K) and in two other cuprates showing static stripe o…
Relationship between charge stripe order and structural phase transitions in LaBaSrCuO
H. Kimura, Y. Noda, H. Goka +5
The nature of charge stripe order and its relationship with structural phase transitions were studied using synchrotron X-ray diffraction in LaBaSrCuO$_…
