Macroscopic polarization in the nominally ergodic relaxor state of lead magnesium niobate
Lukas M. Riemer, Kanghyun Chu, Yang Li +4
Macroscopic polarity and its dynamic response to external electric fields and temperature in the nominally ergodic relaxor phase of pristine lead magnesium niobate crystals and cer…

Nonlinear Flexoelectricity in Non-centrosymmetric Crystals
Kanghyun Chu, Chan-Ho Yang
We analytically derive the elastic, dielectric, piezoelectric, and the flexoelectric phenomenological coefficients as functions of microscopic model parameters such as ionic positi…

Anomalous low-energy phonons in nearly tetragonal BiFeO3 thin films
K. -Y. Choi, S. H. Do, P. Lemmens +5
We present evidence for a concomitant structural and ferroelectric transformation around K in multiferroic BiFeO/LaAlO thin films close to the tetragonal phas…
