Tilt-driven ferrielectricity in PbZrO
Huazhang Zhang, Ying Liu, Carson Carroll +6
The paper demonstrates that adding an octahedral tilt to the antiferroelectric PbZrO₃ structure breaks symmetry and creates a ferrielectric polar phase, confirmed by first‑principl…
Near-room-temperature magnetoelectric coupling engineered through inversion-breaking tilts in a bulk perovskite polytype
Struan Simpson, Urmimala Dey, Martin R. Lees +3
Systematic strategies to design properties such as ferroelectricity or magnetoelectric coupling are well established in simple perovskite materials, but they remain scarce in more…
Alternative origins of polarity in compressively strained SrTiO3-RENiO3 capacitors
Evgenios Stylianidis, Panagiotis Koutsogiannis, Alexander Lione +8
Since its original prediction 25 years ago, room-temperature out-of-plane ferroelectricity in compressively strained SrTiO3 remains an ongoing pursuit. In this work, we investigate…
Theory and Discovery of Electrides
Chengcheng Xiao, Nicholas Bristowe, Arash A. Mostofi
Electrides are materials with electrons localized at interstitial regions of the crystal lattice and have been identified as promising candidates for a variety of applications, inc…
The Microscopic Structure of Stacking Faults in SrNaNbO
Robin Sjökvist, Yining Xie, Zabeada Aslam +4
Stacking faults and other topological defects in ferroics can have a significant influence on the electronic and mechanical properties of the material. Here, regular stacking fault…
Improper-proper ferroelectric competition as a mechanism for multistate polarisation and ferrielectric-like behaviour
Cameron A. M Scott, Finlay D. Morrison, Nicholas. C. Bristowe
In this paper, we re-explore a simple textbook Landau model describing improper ferroelectricity and show that in the limit where both proper and improper instabilities exist and c…
