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 ...
