Aluminum‐Substituted Yttrium Iron Garnet Films With Perpendicular Anisotropy Grown on Silicon by Sputtering

open access: yesAdvanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Ultrathin Al‐substituted YIG films with perpendicular magnetic anisotropy are sputter‐grown directly on Si/SiOx using an ultrathin AlOx buffer layer. Al diffusion reduces the saturation magnetization and stabilizes PMA via magnetoelastic effects. Pt/Al:YIG bilayers exhibit strong spin Hall magnetoresistance and efficient spin–orbit torque switching ...

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

open access: yesAdvanced Physics Research, Volume 5, Issue 6, June 2026.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.
