Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals

Advanced Functional Materials, EarlyView.
In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Large Spin‐Orbit Torque with Multi‐Directional Spin Components in Ni4W

Advanced Materials, EarlyView.
Ni4W is theoretically proposed and experimentally verified as a promising unconventional spin‐orbit torque (SOT) material for generating multi‐directional spins. Epitaxial Ni4W thin films with outstanding crystallinity are grown by magnetron sputtering.

A cohort study comparing the effects of medical cannabis for anxiety patients with and without comorbid sleep disturbance

Neuropsychopharmacology Reports
Background Research on cannabis‐based medicinal products (CBMPs) in anxiety remains inconclusive due to a paucity of high‐quality evidence. Studies indicate a bidirectional relationship between generalized anxiety disorder (GAD) and sleep disruption, but

Glaphene: A Hybridization of 2D Silica Glass and Graphene

Advanced Materials, EarlyView.
‘Glaphene’, a novel hybrid material combining 2D silica glass and graphene, is synthesized via a scalable liquid precursor‐based vapor‐phase growth. This study reveals interlayer hybridization beyond van der Waals interactions, leading to emergent semiconducting behavior.

Low‐Energy, Ultrafast Spin Reorientation at Competing Hybrid Interfaces with Tunable Operating Temperature

Advanced Materials, EarlyView.
A spin reorientation transition is generated at hybrid interfaces of Pt‐Co‐organic molecules in the vicinity of room temperature. This spin reorientation transition happens at an ultrafast scale and is controlled either through electrical current or fs laser pulse, introducing perpendicular magnetic anisotropy in formerly planar magnetised samples ...

Designing Physical Unclonable Functions From Optically Active Materials

Advanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Integrated diamond sapphire laser

Frontiers in Optics, 2003
We use analytic expressions and simulations to examine a model laser gain element formed by integrating diamond and a solid state laser material, such as, Ti:sapphire. The gain element is designed to provide in a single composite structure the thermal management capabilities of diamond and the optical amplification of the laser material.

Revealing the Altermagnetism in Hematite via XMCD Imaging and Anomalous Hall Electrical Transport

Advanced Materials, EarlyView.
This study combines X‐ray magnetic imaging and electrical transport to uncover the anomalous Hall effect in hematite, an insulating oxide exhibiting unconventional altermagnetic properties. Imaging reveals distinct magnetic domains linked to crystal symmetry, and angular‐dependent transport measurements highlight unusual symmetry‐driven conductivity ...
