Topotactic Phase Transition in Epitaxial La0.7Sr0.3MnO3‐δ Films Induced by Oxygen Getter Assisted Thermal Annealing

Small, Volume 22, Issue 7, 2 February 2026.
The perovskite to brownmillerite topotactic phase transition in La0.7Sr0.3MnO3‐δ thin films is achieved through a simple and efficient thermal vacuum annealing that employs bulk aluminum as an active oxygen getter. STEM reveals surface segregation and cation redistribution, while EELS identifies distinct manganese oxidation states across different ...

Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe ${f}_{pe}$/fce ${f}_{ce}$

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.
