Field‐free programmable bipolar magnetic heterostructures for neuromorphic computing

InfoMat, EarlyView.
Neuromorphic computing mimics the brain's efficiency, yet typical memristors lack biological synapses' dual signal control. We introduce a magnetic memristor enabling bidirectional, multi‐state modulation without external fields, validated in image feature extraction and neural clustering.

Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

Laser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Nonlocal Electrical Detection of Spin‐Polarized Surface Currents in the 3D Topological Insulator BiSbTeSe2

physica status solidi (b), EarlyView.
Nonlocal (NL) electrical measurements in the topological insulator BiSbTeSe2 reveal spin‐polarized surface currents, which vanish around 20 K due to increased interactions between bulk and surface states. An enhanced spin‐to‐background ratio in the NL geometry compared to the local geometry provides new insights into spin transport and current pathways
