Octahedral tilts and electronic correlations in La_7/8Sr_1/8MnO_3 (2006)

Geck, J., Wochner, P., Kiele, S., Reutler, P., Revcolevschi, A., Büchner, B.

We present a resonant x-ray scattering study of the octahedral tilt order between 50K and 310K in La_7/8Sr_1/8MnO_3. At the La L_II-edge the resonant (300) reflection probes cooperative tilts of the...

Orbital polaron lattice formation in lightly doped La1-xSrxMnO3 (2005)

Geck, J., Wochner, P., Kiele, S., Klingeler, R., Reutler, P., Revcolevschi, A., ...

By resonant x-ray scattering at the Mn K-edge on La7/8Sr1/8MnO3, we show that an orbital polaron lattice (OPL) develops at the metal-insulator transition of this compound. This orbital reordering...

A 4-unit-cell superstructure in optimally doped YBa2Cu3O6.92 superconductor (2003)

Islam, Zahirul, Liu, X., Sinha, S. K., Lang, J. C., Moss, S. C., Haskel, D., ...

Using high-energy diffraction we show that a 4-unit-cell superstructure, q0=(1/4,0,0), along the shorter Cu-Cu bonds coexists with superconductivity in optimally doped YBCO. A complex set of...

Neutron diffraction study of stripe order in La(2)NiO(4+d) with d=2/15 (1997)

Wochner, P., Tranquada, J. M., Buttrey, D. J., Sachan, V.

We report a detailed neutron scattering study of the ordering of spins and holes in oxygen-doped La(2)NiO(4.133). The single-crystal sample exhibits the same oxygen-interstitial order but better...

Spin Dynamics in an Ordered Stripe Phase (1996)

Tranquada, J. M., Wochner, P., Buttrey, D. J.

Inelastic neutron scattering has been used to measure the low-energy spin excitations in the ordered charge-stripe phase of La(2)NiO(4+d) with d=0.133. Spin-wave-like excitations disperse away from...

Field-Induced Staggered Magnetic Order in La(2)NiO(4.133) (1996)

Tranquada, J. M., Wochner, P., Moodenbaugh, A. R., Buttrey, D. J.

At low temperature the holes doped into the NiO(2) planes of La(2)NiO(4.133) by the excess oxygen collect in diagonal stripes that separate narrow antiferromagnetic domains. The magnetic order drops...
