Light scattering in relaxor ferroelectrics due to domain structure

, 2003
Domain structure of relaxor ferroelectrics was obtained theoretically by T-matrix method. First we discuss numerical aspects of T-matrix computations specific for spheroidal particles and present results of benchmark computations for a simple Chebyshev's

Is There A Pure Electronic Ferroelectric?

Advanced Electronic Materials
Different from traditional ferroelectrics whose polarization stems from ionic displacements mediated by phonons, electronic ferroelectrics exhibit spontaneous polarization originating from polar electronic ordering.
