Charge-Order Pattern of the Low-Temperature Phase of NaV2O5 Uniquely Determined by Resonant X-Ray Scattering from Monoclinic Single Domain
Kenji Ohwada, Yasuhiko Fujii, Yuya Katsuki +7
The present resonant x-ray scattering from each of monoclinically-split single domains of NaV2O5 has critically enhanced contrast between V4+ and V5+ ions strong enough to lead to…
Neutron Diffraction Study of Field Cooling Effects on Relaxor Ferroelectrics Pb[(Zn_{1/3} Nb_{2/3})_{0.92} Ti_{0.08}] O_{3}
Kenji Ohwada, Kazuma Hirota, Paul W. Rehrig +2
High-temperature (T) and high-electric-field (E) effects on Pb[(Zn_{1/3} Nb_{2/3})_{0.92} Ti_{0.08}]O_3 (PZN-8%PT) were studied comprehensively by neutron diffraction in the ranges…
Low-Temperature Structure of the Quarter-Filled Ladder Compound alpha'-NaV2O5
Hiroshi Sawa, Emi Ninomiya, Tetsuo Ohama +7
The low-temperature (LT) superstructure of -NaVO was determined by synchrotron radiation x-ray diffraction. Below the phase transition temperature associated with atomi…
Neutron Diffraction Study of the Irreversible R-MA-MC Phase Transition in Single Crystal Pb[(Zn1/3Nb2/3)1-xTix]O3
Kenji Ohwada, Kazuma Hirota, Paul W. Rehrig +5
Single crystals of the relaxor PZN-xPT display an enormously strong piezoelectric character. Recent x-ray scattering studies have revealed novel electric-field induced phase transi…
The "devil's staircase" type phase transition in NaV2O5 under high pressure
K. Ohwada, Y. Fujii, N. Takesue +12
The "devil's staircase" type phase transition in the quarter-filled spin-ladder compound NaV2O5 has been discovered at low temperature and high pressure by synchrotron radiation x-…
X-Ray Diffuse Scattering Study on Ionic-Pair Displacement Correlations in Relaxor Lead Magnesium Niobate
Naohisa Takesue, Yasuhiko Fujii, Hoydoo You
Ionic-pair equal-time displacement correlations in relaxor lead magnesium niobate, , have been investigated at room temperature in terms of an x-ray diff…
