Reversibly controlled ternary polar states and ferroelectric bias promoted by boosting square-tensile-strain
Jun Han Lee, Nguyen Xuan Duong, Min-Hyoung Jung +23
Interaction between dipoles often emerges intriguing physical phenomena, such as exchange bias in the magnetic heterostructures and magnetoelectric effect in multiferroics, which l…
Strain-gradient-induced magnetic anisotropy in straight-stripe mixed-phase bismuth ferrites: An insight into flexomagnetic phenomenon
Jin Hong Lee, Kwang-Eun Kim, Byung-Kweon Jang +7
Implementation of antiferromagnetic compounds as active elements in spintronics has been hindered by their insensitive nature against external perturbations which causes difficulti…
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…
Near-field examination of perovskite-based superlenses and superlens-enhanced probe-object coupling
Susanne C. Kehr, Yongmin M. Liu, L. W. Martin +11
A planar slab of negative index material works as a superlens with sub-diffraction-limited imaging resolution, since propagating waves are focused and, moreover, evanescent waves a…
