First-order polarization process as an alternative to antiferroelectricity
Louis Bastogne, Lukas Korosec, Evgenios Stylianidis +6
Antiferroelectrics generate significant interest since their polarization versus electric field (PE) curves show typical double-hysteresis loops appealing for various applications.…
Assessing the nature of nanoscale ferroelectric domain walls in lead titanate multilayers
Edoardo Zatterin, Petr Ondrejkovic, Louis Bastogne +12
The observation of unexpected polarisation textures such as vortices, skyrmions and merons in various oxide heterostructures has challenged the widely accepted picture of ferroelec…
Emergent electronic landscapes in a novel valence-ordered nickelate with tri-component nickel coordination
Aravind Raji, Zhengang Dong, Victor Porée +11
The metal-hydride-based topochemical reduction process has produced novel thermodynamically unstable phases across various transition metal oxide series with unusual crystal struct…
Nanoscale domain engineering in SrRuO thin films
Céline Lichtensteiger, Chia-Ping Su, Iaroslav Gaponenko +5
We investigate nanoscale domain engineering via epitaxial coupling in a set of SrRuO/PbTiO/SrRuO heterostructures epitaxially grown on (110)-oriented DyScO subs…
Mapping Orthorhombic Domains with Geometrical Phase Analysis in Rare-Earth Nickelate Heterostructures
Bernat Mundet, Marios Hadjimichael, Jennifer Fowlie +5
Most perovskite oxides belong to the Pbnm space group, composed by an anisotropic unit cell, A-site antipolar displacements and oxygen octahedral tilts. Mapping the orientation of…
