Optoelectronic Devices for In‐Sensor Computing

Advanced Materials, EarlyView.
The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...

SciAgents: Automating Scientific Discovery Through Bioinspired Multi‐Agent Intelligent Graph Reasoning

Advanced Materials, EarlyView.
The SciAgents AI model drives hypothesis generation by harnessing multi‐agent graph reasoning, extracting insights from knowledge graphs constructed from scientific papers. Each agent plays a specific role: the Ontologist defines concepts, the Scientists draft and refine proposals, and the Critic reviews.

Orbital Topology of Chiral Crystals for Orbitronics

Advanced Materials, EarlyView.
Chirality is ubiquitous in nature and constitutional for life. In chiral materials the intrinsic handedness, defined by their crystal structure, becomes a main driver for a novel electronic topology that is based on the orbital angular momentum rather than the electron spin.

Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

Advanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.
