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…
Disappearance of antiferromagnetic spin excitations in over-doped LaSrCuO
S. Wakimoto, K. Yamada, J. M. Tranquada +3
Magnetic excitations in the energy range up to 100 meV are studied for over-doped LaSrCuO with and 0.30, using time-of-flight neutron spectroscopy. Com…
Magnetic neutron scattering in hole doped cuprate superconductors
R. J. Birgeneau, C. Stock, J. M. Tranquada +1
A review is presented of the static and dynamic magnetic properties of hole-doped cuprate superconductors measured with neutron scattering. A wide variety of experiments are descri…
Unidirectional Diagonal Order and 3D Stacking of Charge Stripes in Orthorhombic Pr1.67Sr0.33NiO4 and Nd1.67Sr0.33NiO4
M. Huecker, M. v. Zimmermann, R. Klingeler +9
The interplay between crystal symmetry and charge stripe order in Pr1.67Sr0.33NiO4 and Nd1.67Sr0.33NiO4 has been studied by means of single crystal x-ray diffraction. In contrast t…
Charge order, metallic behavior and superconductivity in La_{2-x}Ba_xCuO_4 with x=1/8
C. C. Homes, S. V. Dordevic, G. D. Gu +3
The ab-plane optical properties of a cleaved single crystal of La_{2-x}Ba_xCuO_4 for x=1/8 (T_c ~ 2.4 K) have been measured over a wide frequency and temperature range. The low-fre…
