Realization of Complex‐Shaped Magnetic Nanotubes with 3D Printing and Electrodeposition

Advanced Functional Materials, EarlyView.
Complex‐shaped magnetic nanotubes were fabricated by coating three‐dimensional nanoscaffolds fabricated with focused electron beam induced deposition with a magnetic coating via electrodeposition. X‐ray magnetic microscopy and simulations revealed an azimuthal magnetic configuration within the nanotubes and pinning of domain walls at curved vertices ...

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

Advanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...

Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

Advanced Functional Materials, EarlyView.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.

Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe

Advanced Functional Materials, EarlyView.
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

Advanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.

Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3

Advanced Functional Materials, EarlyView.
Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...
