Customizable Fully Structured Vector Trajectory Beams in the Focal Plane via a Single‐Layer Metasurface

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
This work introduces a unique class of structured light—trajectory beams—where all degrees of freedom evolve dynamically along the predefined trajectory. By employing computer‐generated holography, single‐layer metasurfaces achieve the complete decoupling of trajectory shape and the distributions of amplitude, phase, and polarization along the path ...

Acquisition of Self‐Reversed Magnetization in Greigite Driven by Antiparallel Vortex‐Core Coupling During Low‐Temperature Oxidation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Self‐reversed magnetization, acquired antiparallel to the external field, can complicate the interpretation of paleomagnetic directional records, particularly in altered greigite‐bearing sediments with anomalous magnetizations. The underlying physical process for this self‐reversal remains poorly constrained.

Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.

Evaluating TEMPO Formaldehyde Retrievals With Co‐Located Ground‐Based FTIR and Pandora Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Formaldehyde (HCHO) is an important proxy for volatile organic compounds and photochemical activity, with significant implications for air quality and atmospheric chemistry. The recently launched geostationary satellite instrument Tropospheric Emissions: Monitoring of Pollution (TEMPO) provides the first‐ever hourly observations of HCHO and ...
