Microdomain dynamics in single-crystalBaTiO3during paraelectric-ferroelectric phase transition measured with time-of-flight neutron scattering

Size-driven ferroelectric–paraelectric phase transition in TGS nanocomposites

Dielectric properties of porous glass nanocomposites with TGS crystals embedded into six porous matrices with average pore size from 5 to 312 nm were investigated in the temperature range from 280 to 380 K at selected frequencies. The results are discussed based on the effect of the particle size on the phase transition temperature of TGS nanocomposites. Temperature-size phase diagram of TGS co...

Crystal structure and the paraelectric-to-ferroelectric phase transition of nanoscale BaTiO3.

We have investigated the paraelectric-to-ferroelectric phase transition of various sizes of nanocrystalline barium titanate (BaTiO3) by using temperature-dependent Raman spectroscopy and powder X-ray diffraction (XRD). Synchrotron X-ray scattering has been used to elucidate the room temperature structures of particles of different sizes by using both Rietveld refinement and pair distribution fu...
