High q-resolution neutron scattering technique using triple-axis spectrometers
Guangyong Xu, P. M. Gehring, V. J. Ghosh +1
We present a new technique which brings a substantial increase of the wave-vector -resolution of triple-axis-spectrometers by matching the measurement wave-vector to the ref…
Evidence of decoupled lattice distortion and ferroelectric polarization in the relaxor system PMN-xPT
Guangyong Xu, D. Viehland, J. F. Li +2
We report high -resolution neutron scattering data on PMN-PT single crystals with and 27%. No rhombohedral distortion occurs in the 20PT sample for temperatures as lo…
Dynamics and Structure of PMN and PZN
G. Shirane, Guangyong Xu, P. M. Gehring
A review is given of recent neutron and x-ray scattering studies of the lead-oxide perovskite relaxor systems Pb(Zn1/3Nb2/3)O3-xPbTiO3 and Pb(Mg1/3Nb2/3)O3-xPbTiO3. X-ray measureme…
Structure and Dynamics of the Ferroelectric Relaxors Pb(Mg1/3Nb2/3)O3 and Pb(Zn1/3Nb2/3)O3
G. Shirane, P. M. Gehring
We review some of the current research on two of the ultra-high piezoelectric relaxors Pb(Mg1/3Nb2/3)O3 (PMN) and Pb(Zn1/3Nb2/3)O3 (PZN). The discovery of a monoclinic phase in Pb(…
Soft Phonon Anomalies in Relaxor Ferroelectrics
G. Shirane, P. M. Gehring
A review is given of the phonon anomalies, which have been termed ``waterfalls,'' that were recently discovered through a series of neutron inelastic scattering measurements on the…
Neutron Scattering Study of Elastic Magnetic Signals in Superconducting La1.94Sr0.06Cu4
S. Wakimoto, K. Yamada, S. Ueki +8
Recent neutron-scattering experiments on La(2-x)Sr(x)CuO4 single crystals by Wakimoto et al. have revealed that elastic magnetic peaks appear at low temperatures in both insulating…
