Antiferroelectric Phase Transitions Under Electric Fields: A Review of Physics and Applications

Interdisciplinary Materials, EarlyView.
Field‐induced phase transitions in antiferroelectric materials, driven by electric field, temperature, or stress, enable diverse applications including energy storage, electrocaloric cooling, and negative capacitance. These transitions are regulated through compositional design, strain engineering, heterostructure, and size effect, providing a unified ...

Processing and characterization of lead-free ceramics on the base of sodium–potassium niobate [PDF]

Journal of Advanced Dielectrics, 2018
Lead-free sodium–potassium niobate-based piezoelectric materials are most intensively studied in order to replace the widely used Pb-based ones. In this work, the effects of modification of compositions by donor and acceptor dopants in the A- and B-sites

Imprint effect in PZT thin films at compositions around the morphotropic phase boundary [PDF]

, 2016
Piezoeresponse force microscopy (PFM) and local piezoresponse hysteresis loops were used to study the imprint effect in PbZr1-xTixO3 thin films at compositions around the morphotropic phase boundary (MPB).

Combined Electrostatic and Strain Engineering of BiFeO3 Thin Films at the Morphotropic Phase Boundary

Advanced Electronic Materials
Multiferroic BiFeO3 exhibits a morphotropic phase boundary at large compressive strain that merges metastable phases of tetragonal (T) and rhombohedral (R) character resulting in giant ferroelectric and electromechanical responses.

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Influence of lanthanum doping on the morphotropic phase boundary of lead zirconate titanate [PDF]

, 2010
A phase diagram for morphotropic (Pb0.985La0.01)(Zr1−xTix)O3 is proposed based on a combination of X-ray and neutron powder diffraction experiments and complemented by transmission electron microscopy.

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...
