Ferroelectricity in tetragonal ZrO thin films
Ali El Boutaybi, Thomas Maroutian, Ludovic Largeau +10
We report on the crystal structure and ferroelectric properties of epitaxial ZrO films ranging from 7 to 42 nm thickness grown on LaSrMnO-buffered (110)-o…
Electro-optic properties of ZrO2, HfO2 and LiNbO3 ferroelectric phases: A comprehensive and comparative study with density functional theory
Ali El Boutaybi, Panagiotis Karamanis, Thomas Maroutian +4
We report the Pockels electro-optic properties of ZrO2 and HfO2 orthorhombic Pbc21 and rhombohedral R3m ferroelectric phases, and we compare them to the well-known LiNbO3 Pockels m…
Stabilization of the epitaxial rhombohedral ferroelectric phase in ZrO2 by surface energy
Ali El Boutaybi, Thomas Maroutian, Ludovic Largeau +2
Doped HfO2 and HfO2-ZrO2 compounds are gaining significant interest thanks to their ferroelectric properties in ultrathin films. Here, we show that ZrO2 could be a playground for d…
Magnetic domain wall motion in SrRuO thin films
Martin Zahradník, Klára Uhlířová, Thomas Maroutian +4
Influence of substrate miscut on magnetization dynamics in SrRuO (SRO) thin films was studied. Two films were grown on SrTiO substrates with high () and low…
Magneto-ionic control of spin polarization in magnetic tunnel junctions
Yingfen Wei, Sylvia Matzen, Cynthia P. Quinteros +4
Magnetic tunnel junctions (MTJs) with Hf0.5Zr0.5O2 barriers are reported to show both tunneling magnetoresistance effect (TMR) and tunneling electroresistance effect (TER), display…
Conduction mechanism and switchable photovoltaic effect in (111) oriented BiFeMnO thin film
Jamal Belhadi, J. Ruvalcaba, S. Yousfi +5
Epitaxial 200nm BiFeMnO (BFO) film was grown by pulsed laser deposition on (111) oriented SrTiO3 substrate buffered with a 50nm thick SrRuO electrode.…
