Theory of the Morphotropic Phase Boundary

Ferroelectrics, 2001
A Landau theory is presented for the morphotropic phase boundaries in the solid solution system of perovskite-type oxide ferroelectrics. The origin of useful functions of materials located close to the morphotropic phase boundary are attributed to the isotropy of the thermodynamic potential.

Relaxor Behavior and Morphotropic Phase Boundary in a Simple Model [PDF]

Journal of the Physical Society of Japan, 2013
A simple model to reproduce strong enhancement of dielectric response near the morphotropic phase boundary (MPB) is proposed. This model consists of long-range dipole-dipole interaction and compositional chemical disorder incorporated by the variation in lengths of dipole moments.

Morphotropic Phase Boundary in Polarized Organic Piezoelectric Materials

Physical Review Letters, 2023
Designing the morphotropic phase boundary (MPB) has been the most sought-after approach to achieve high piezoelectric performance of piezoelectric materials. However, MPB has not yet been found in the polarized organic piezoelectric materials. Here, we discover MPB with biphasic competition of β and 3/1-helical phases in the polarized piezoelectric ...

Ferroelectric Polymers Exhibiting Behaviour Reminiscent of a Morphotropic Phase Boundary

Nature, 2018
Piezoelectricity-the direct interconversion between mechanical and electrical energies-is usually remarkably enhanced at the morphotropic phase boundary of ferroelectric materials1-4, which marks a transition region in the phase diagram of piezoelectric materials and bridges two competing phases with distinct symmetries1,5. Such enhancement has enabled

Polarization Spinodal at Ferroelectric Morphotropic Phase Boundary

Physical Review Letters, 2020
Here, we report a new phenomenon of uniform and continuous transformation of a single polarization domain into alternating nanodomains of two polarization vectors with the same magnitude but different directions at ferroelectric morphotropic phase Boundary (MPB).

Origin of morphotropic phase boundaries in ferroelectrics

Nature, 2008
A piezoelectric material is one that generates a voltage in response to a mechanical strain (and vice versa). The most useful piezoelectric materials display a transition region in their composition phase diagrams, known as a morphotropic phase boundary, where the crystal structure changes abruptly and the electromechanical properties are maximal. As a
