Magneto‐X Effects in Magnetic Soft Materials and Their Applications

Advanced Science, Volume 13, Issue 18, 27 March 2026.
This review systematically explores magnetic soft materials (MSMs), a novel class of composites that transform under magnetic fields. It catalogs fundamental “Magneto‐X” effects, classifies materials by their matrix and magnetic fillers, and highlights transformative applications in soft robotics, biomedical devices, flexible electronics, etc. Finally,

Vacancy‐Controlled Lattice Dynamics and Magnetism in Mn‐Doped CeO2−δ Nanocrystals

Annalen der Physik, Volume 538, Issue 3, March 2026.
ABSTRACT Mn‐doped CeO2−δ${\rm CeO}_{2-\delta }$ nanocrystals provide a model system to quantify how defect chemistry controls emergent magnetism in a wide‐gap oxide. Single‐phase fluorite Ce1−xMnxO2−δ${\rm Ce}_{1-x}{\rm Mn}_x{\rm O}_{2-\delta }$ (0≤x≤0.09$0 \le x \le 0.09$) nanocrystals exhibit nonmonotonic changes in lattice parameter, microstrain ...

Magnetic Reversals During the Deccan Volcanism: Paleomagnetic Insights From the Pachmarhi Dykes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The three main dyke swarms that are linked to the Deccan Continental Flood Basalts are the Nasik‐Pune, Western Coastal, and Narmada‐Satpura‐Tapi (N‐S‐T) swarms. Encompassing approximately 244 mapped basaltic dykes, mainly trending E‐W and positioned along an ancient tectonic zone, the Pachmarhi dyke swarm is situated in the eastern N‐S‐T ...
