Metastable morphotropic phase boundary state in the multiferroic BiFeO3-PbTiO3

, 2013
Temperature-time study of the magnetoelectric multiferroic (1-x)BiFeO3-(x)PbTiO3 by x-ray and electron diffraction on the reported morphotropic phase boundary (MPB) compositions revealed that this MPB does not correspond to the equilibrium state. The MPB

Equilibrium phases in the multiferroic BiFeO3-PbTiO3 system – a revisit

EPJ Web of Conferences, 2014
The(1-x) BiFeO3-(x) PbTiO3 solid solution exhibiting a Morphotropic Phase Boundary (MPB) has attracted considerable attention recently because of its unique features such as multiferroic, high Curie point (TC ~ 700°C) and giant tetragonality (c/a -1 ~ 0 ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Rhombohedral-Orthorhombic Morphotropic Phase Boundary in BiFeO3-based Multiferroics: First-Principles Prediction

, 2012
A pseudo-binary solid solution formed with two structurally dissimilar end members possesses a structural phase boundary, commonly called the morphotropic phase boundary (MPB). Many of the technologically useful piezoelectric oxides exhibit their maximum

Piezoelectric ceramics with high piezoelectricity and broad temperature usage range

Journal of Materiomics, 2021
There is a general observation that the Curie temperature and piezoelectric property of the ferroelectric ceramics can be enhanced only at the expense of each other, i.e., higher piezoelectricity, lower Curie temperature, thus, limits their applications ...
