Enhanced Spin‐Reorientation Transition and Polarization in DyFeO3 Thin Films

Advanced Electronic Materials, EarlyView.
Epitaxial strain in antiferromagnetic orthoferrite thin films enhances known bulk properties into a parameter range that makes them more accessible for potential applications. We show that bulk polar properties move from 4 K towards room temperature and the magnetic field‐induced AFM to FM spin‐flip in the paramagnetic Dy lattice when applying small ...

Oxygen‐Scavenging‐Driven Interlayer Engineering for Balancing Linearity and Retention in IGZO Synaptic Memristors

Advanced Electronic Materials, EarlyView.
Oxygen‐scavenging‐induced self‐formed interlayers regulate Schottky‐barrier modulation in IGZO memristors, producing a fundamental trade‐off between synaptic update linearity and retention. A preserved AlOx interlayer moderates voltage distribution and enables gradual, nearly linear conductance updates, whereas a soft‐broken SiO2 interlayer provides a ...

Photo‐Dielectric Synaptic Plasticity in Zn‐Doped BaAl2O4

Advanced Electronic Materials, EarlyView.
Localized photoexcited electrons in 2٠ZnO3‐VO defect complexes enable persistent and programmable photo‐dielectric modulation in Zn‐substituted BaAl2O4, giving rise to synaptic‐like plasticity under pulsed light irradiation. ABSTRACT Optically reconfigurable dielectrics represent an emerging route toward low‐power, spatially addressable neuromorphic ...
