Journal ArticleDOI
Hybrid improper ferroelectricity: a mechanism for controllable polarization-magnetization coupling.
TL;DR: The term "hybrid" improper ferroelectricity is used to describe this phenomenon and discuss how control over magnetism is achieved through these functional antiferrodistortive octahedron rotations.
Journal ArticleDOI
Why Are There So Few Perovskite Ferroelectrics
TL;DR: In this paper, a combination of symmetry arguments and first-principles calculations is used to explore the connection between structural distortions and ferroelectricity in the perovskite family of materials.
Journal ArticleDOI
Turning ABO3 Antiferroelectrics into Ferroelectrics: Design Rules for Practical Rotation‐Driven Ferroelectricity in Double Perovskites and A3B2O7 Ruddlesden‐Popper Compounds
TL;DR: In this paper, a complete theory is formulated for a novel form of ferroelectricity, whereby a spontaneous and switchable polarization emerges from the destruction of an antiferroelectric state due to octahedral rotations and ordered cation sublattices.
Journal ArticleDOI
Understanding ferroelectricity in layered perovskites: new ideas and insights from theory and experiments
TL;DR: This Perspective highlights recent theoretical and experimental studies that have shown how a combination of non-polar structural distortions can give rise to polar structures or ferroelectricity in several families of layered perovskites and discusses the crystal chemical origin of the polarization in each of these families.

TL;DR: In this unique system an increase in the separation between the (SrO)2 planes, which can be achieved by changing n, bolsters the local ferroelectric instability and can be exploited to achieve a figure of merit at room temperature that rivals all known tunable microwave dielectrics.
