Proximity‐Tuned Magnetic and Transport Anomalies in All‐Epitaxial Fe5−xGeTe2/WSe2 Van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
All‐epitaxial and scalable ferromagnetic/non‐magnetic Fe5−xGeTe2/WSe2 van der Waals (vdW) heterostructures exhibiting room‐temperature magnetism and perpendicular magnetic anisotropy (PMA) are realized. The system displays proximity‐tuned magnetic anisotropy, thickness‐dependent unconventional Hall effects, and temperature‐dependent sign reversal of ...

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

Advanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

Switching of Perpendicular Magnetization via ac Spin-Orbit Torque

, 2018
We theoretically and numerically investigate the switching of perpendicular magnetization by ac spin-orbit torque. We find that the threshold switching current for ac spin-orbit torque is much smaller than that for dc spin-orbit torque.

Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides

Advanced Functional Materials, EarlyView.
Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

Giant, Linearly Increasing Spin–Orbit Torque Efficiency in Symmetry-Broken Spin–Orbit Torque Superlattices

, 2023
Magnetic heterostructures with high spin–orbit torque efficiency and low impedance have great promise for low-power spintronic technologies. We report a symmetry-broken spin–orbit superlattice [Pt0.75Cu0.25/Co/Ta]n, in which the dampinglike spin–orbit ...

Modulation of Surface‐Associated Transport in (Bi1‐xSbx)2Te3 via Battery‐ Inspired Solid‐State Iontronic Gating

Advanced Functional Materials, EarlyView.
Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...
