Condensation of the atomic relaxation vibrations in lead-magnesium-niobate at
Sergey Prosandeev, Igor P. Raevski, Maria A. Malitskaya +4
We present neutron diffraction, dielectric permittivity and photoconductivity measurements, evidencing that lead-magnesium niobate experiences a diffuse phase transformation betwee…
Direct Observation and Quantitative Analysis of Anti-ferroelectric Fluctuations in Pb(Mg1/3Nb2/3)O3 Relaxor
A. Tkachuk, Haydn Chen
Synchrotron x-ray scattering studies of anti-ferroelectric nanoregions (AFR) as fluctuations, which give rise to 1/2(hk0) superlattice reflections (alpha spots), were systematicall…
Synchrotron x-ray Studies of Superlattice Ordering in Pb(Mg1/3Nb2/3)O3 Single Crystals Doped with PbTiO3
A. Tkachuk, Paul Zschack, Eugene Colla +1
The temperature dependence of the superlattice reflections: a) F spots and b) alpha spots in a lead magnesium niobate (PMN) single crystals containing 0% and 6% of PbTiO3 (PT) has…
Anti-ferrodistortive Nanodomains in PMN Relaxor
A. Tkachuk, Haydn Chen
Temperature dependent studies of the 1/2(hk0) superlattice reflections αspots by synchrotron x-ray scattering measurements were performed in (PMN) and (PMN-xPT) with Ti doping x<0.…
