Ferroelectric and Piezoelectric Properties of (Mg1/3Nb2/3)4+-Doped Bismuth Sodium Titanate Ceramics

open access: yesCeramics
Lead-free (Bi1/2Na1/2)(Ti1−x(Mg1/3Nb2/3)x)O3 ceramics were synthesized using the solid-phase method, and the effects of varying (Mg1/3Nb2/3)4+ content, substituting for Ti4+ ions at the B-site of the BNT perovskite lattice, on piezoelectric performance ...

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

open access: yesENERGY &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.

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

open access: yesElectron, 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 ...

Light‐Modulated Exchange Bias in Multiferroic Heterostructures

open access: yesElectron, EarlyView.
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.
