Influence of grinding and pressing of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure and magnetic properties [PDF]

Science of Sintering
Mixing the powders Fe (50.0 wt%), BaTiO3 (47.0 wt%) and TiO2 (3.0wt%) provides a mixture consisting of a matrix of smaller particles BaTiO3 in which larger particles Fe and TiO2 were embedded.

Thermomechanics of multiferroics

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Generally understood ferroic media have been investigated by many authors. The majority of them have dealt with the electromagnetic nature of the domain structure of crystalline or amorphous solids. However, there exist also materials that have an internal ordered structure from the mechanical (elastic) point of view. They are called ferroelastics. The

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

Experimental investigations on multiferroic materials

, 2019
By definition, a single phase multiferroic is a material that simultaneously possesses two or more so-called ferroic order parameters such as ferroelectricity, ferromagnetism and ferroelasticity.

PVDF-based multiferroic

, 2020
Multiferroic materials-able to show a good magnetoelectric effect-have been subjected to increasing research in recent years because of the possibility to combine electric and magnetic properties at the same time in the same material.

A Flexible Poling‐Free Piezoelectric Energy Harvester Based on Gradient Ti‐Doped BiFeO3 Films

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A self‐aligned polarization is realized in compositional gradient Ti‐doped BiFeO3 films via the formation of defect dipoles and strain gradient. The self‐poling behavior is robust to resist high electric field and elevated temperature. The fabricated poling‐free piezoelectric energy harvester delivers output comparable to the poled ones.

Imaging of a multiferroic domain wall in a non-multiferroic environment

Matter
Compared with the surrounding bulk, the domain walls of materials exhibiting spontaneous long-range order exhibit significant changes in properties. The conducting domain walls in ferroelectrics are of great interest, for example, for their potential in rewriteable electric circuits.

Magneto‐Electrochemical Effect on La‐Doped GaFeO3 as a Supercapacitor Electrode for Energy Storage

Electron, EarlyView.
The electrochemical performance of La‐doped Gallium Ferrite (La‐doped GaFeO3 ${\text{GaFeO}}_{3}$) synthesizes via a conventional solid‐state reaction method; this has been studied by the application of an external magnetic fields. ABSTRACT The electrochemical performance of La‐doped GaFeO3 ${\text{GaFeO}}_{3}$ synthesizes via a conventional solid ...
