Hidden structural transition in epitaxial CaSrIrO/SrTiO thin film
W. T. Jin, H. Gretarsson, S. Y. Jang +3
A structural transition in an ABO perovskite thin film involving the change of the BO octahedral rotation pattern can be hidden under the global lattice symmetry impose…
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…
The electronic structure of epitaxially stabilized 5d perovskite Ca_{1-x}Sr_xIrO_3 (x = 0, 0.5, and 1) thin films: the role of strong spin-orbit coupling
S. Y. Jang, H. S. Kim, S. J. Moon +4
We have investigated the electronic structure of meta-stable perovskite Ca1-xSrxIrO3 (x = 0, 0.5, and 1) thin films using transport measurements, optical spectroscopy, and first-pr…
Electric-field-controlled directional growth of ferroelectric domains in multiferroic BiFeO3 films
T. H. Kim, S. -H. Baek, S. M. Yang +7
We describe the directional growth of ferroelectric domains in a multiferroic BiFeO3 thin film, which was grown epitaxially on a vicinal (001) SrTiO3 substrate. A detailed structur…
