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.

Light‐Modulated Exchange Bias in Multiferroic Heterostructures

Electron, 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.

Spin‐Polarized Magnetic Metal Electrodes for Magnetic Tunnel Junctions

MetalMat, EarlyView.
This perspective surveys spin‐polarized magnetic metal electrodes for magnetic tunnel junctions, systematically covering conventional ferromagnets, collinear/noncollinear antiferromagnets, and emergent altermagnets. It compares tunneling polarization origins across these classes and emphasizes that effective electrode polarization is a momentum ...
