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.

A Solventless Melt Route to Polymer/Mixed‐Metal Sulfide Nanocomposites: Case Study on NiCo2S4/PVP

Journal of Polymer Science, EarlyView.
Solvent‐free thermolysis of metal (Ni, Co)‐ xanthate precursors in PVP enables the in situ formation of NiCo2S4 nanoparticles embedded within the polymer matrix. ABSTRACT Polymer‐inorganic nanocomposites are commonly prepared using solution‐based approaches that rely on solvents, often toxic or costly, and multi‐step processing, which can limit ...

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Large Unsaturated Magnetoresistance in Gated MoS2 Flakes

Small, EarlyView.
Magnetotransport investigation of layered MoS2 crystals in field‐effect devices reveals strong dependence on thickness and carrier density. Monolayer MoS2 exhibits the highest magnetoresistance of 680%. A combination of density functional theory and Boltzmann transport equation simulations shows that band transport is not causing the magnetic behavior,

Automatic calculation of symmetry‐adapted tensors under spin‐group symmetry: STENSOR, a new tool of the Bilbao Crystallographic Server

Journal of Applied Crystallography, EarlyView.
STENSOR automatically computes symmetry‐adapted tensors under spin and magnetic point groups. It generates tensors for both spin and magnetic point groups from structural data files or spin‐group generators. The comparison permits separation of the effects due to spin–orbit coupling from non‐relativistic contributions, as illustrated by examples.We ...
