Experimental verification of polar structures in ultrathin BaTiO_{3} layers using resonant x-ray reflectivity
Kook Tae Kim, Yeong Jae Shinb, Sung-Jin Kang +6
Functional devices with ultrathin ferroelectric layers have been attracted as a promising candidate for next-generation memory and logic device applications. Using the ultrathin fe…
Flexoelectric control of a ferromagnetic metal
Wei Peng, Se Young Park, Chang Jae Roh +16
Electric fields have played a key role in discovering and controlling exotic electronic states of condensed matter. However, electric fields usually do not work in metals as free c…
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,…
Effects of heat dissipation on unipolar resistance switching in Pt/NiO/Pt capacitors
S. H. Chang, S. C. Chae, S. B. Lee +8
We fabricated Pt/NiO/Pt capacitor structures with various bottom electrode thicknesses, , and investigated their resistance switching behaviors. The capacitors with $t_{BE}…
Optical and magneto-optical properties of ferromagnetic full-Heusler films: experiments and first-principles calculations
F. Ricci, S. Picozzi, A. Continenza +5
We report a joint theoretical and experimental study focused on understanding the optical and magneto-optical properties of Co-based full-Heusler compounds. We show that magneto-op…
