Giant Flexoelectric Effect in Ferroelectric Epitaxial Thin Films
Daesu Lee, A. Yoon, S. Y. Jang +5
We report on nanoscale strain gradients in ferroelectric HoMnO3 epitaxial thin films, resulting in a giant flexoelectric effect. Using grazing-incidence in-plane X-ray diffraction,…

Charge states and magnetic ordering in LaMnO3/SrTiO3 superlattices
Woo Seok Choi, D. W. Jeong, S. S. A. Seo +5
We investigated the magnetic and optical properties of [(LaMnO3)n/(SrTiO3)8]20 (n = 1, 2, and 8) superlattices grown by pulsed laser deposition. We found a weak ferromagnetic and s…

Step bunching-induced vertical lattice mismatch and crystallographic tilt in vicinal BiFeO3(001) films
T. H. Kim, S. H. Baek, S. Y. Jang +7
Epitaxial (001) BiFeO3 thin films grown on vicinal SrTiO3 substrates are under large anisotropic stress from the substrates. The variations of the crystallographic tilt angle and t…
