First-order polarization process as an alternative to antiferroelectricity
Louis Bastogne, Lukas Korosec, Evgenios Stylianidis +7
Antiferroelectrics generate significant interest since their polarization versus electric field (P-E) 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…
Mapping the complex evolution of ferroelastic/ferroelectric domain patterns in epitaxially strained PbTiO3 heterostructures
Céline Lichtensteiger, Marios Hadjimichael, Edoardo Zatterin +6
We study the complex ferroelastic/ferroelectric domain structure in the prototypical ferroelectric PbTiO3 epitaxially strained on (110)o-oriented DyScO3 substrates, using a combina…
Intrinsic magnetism in superconducting infinite-layer nickelates
Jennifer Fowlie, Marios Hadjimichael, Maria M. Martins +10
The discovery of superconductivity in NdSrNiO [1] introduced a new family of layered nickelate superconductors that has now been extended to include a range of…
Domain Wall Orientations in Ferroelectric Superlattices Probed with Synchrotron X-Ray Diffraction
Marios Hadjimichael, Edoardo Zatterin, Stéphanie Fernandez-Peña +2
Ferroelectric domains in PbTiO/SrTiO superlattices were studied using synchrotron X-ray diffraction. Macroscopic measurements revealed a change in the domain wall orientati…
Striped nanoscale phase separation at the metal-insulator transition of heteroepitaxial nickelates
Giordano Mattoni, Pavlo Zubko, Francesco Maccherozzi +11
Nucleation processes of mixed-phase states are an intrinsic characteristic of first-order phase transitions, typically related to local symmetry breaking. Direct observation of eme…
Quantum criticality in a uniaxial organic ferroelectric
S. E. Rowley, M. Hadjimichael, M. N. Ali +4
Tris-sarcosine calcium chloride (TSCC) is a highly uniaxial ferroelectric with a Curie temperature of approximately 130K. By suppressing ferroelectricity with bromine substitution…
