Recent progress of the exchange bias based on 2D van der Waals ferromagnet

InfoScience, EarlyView.
Ultrathin magnetic materials could help make smaller, energy‐efficient memories, but their magnetic states must remain stable and controllable. This review brings together recent research on exchange bias, a magnetic pinning effect in layered materials, and explains how interfaces and electrical, thermal or mechanical controls can tune it, with optical

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 ...

Design Methodologies for STT-MRAM (Spin-Torque Transfer Magnetic Random Access Memory) Sensing Circuits

IEICE Transactions on Electronics, 2010
Spin-torque transfer magnetic random access memory (STT-MRAM) is a promising technology for next generation nonvolatile universal memory because it reduces the high write current required by conventional MRAM and enables write current scaling as technology becomes smaller in size.
