Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

Advanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Emplacement Conditions and Alteration of Volcanic Deposits Inferred From Magnetic Properties of the ICDP Eger Drill Site S4 (Bažina Maar), Czechia

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Titanomagnetite in alkaline maar deposits exhibits variable syn‐ and post‐crystallization alteration linked to wet emplacement and groundwater fluctuations, which remain poorly documented. Magnetic and mineralogical analyses of lapilli, scoria, and basalt from ICDP Eger drill cores S4 and S4b (Bažina maar, western Eger Graben, Czechia) reveal ...

Designing Stable Periodic Magnetization Textures by Tailoring Anisotropies and Applying Geometrical Transformation

Advanced Functional Materials, Volume 36, Issue 53, 2 July 2026.
This work explores the possibility to design stable periodic magnetization textures by transforming a 2D film into a rolled‐up 3D architecture and back. In case of an isotropic exchange‐biased layer architecture, the magnetization encoded in the 3D state evolves into a spin‐spiral pattern with controlled periodicity after unrolling.

Thermomagnetic analysis applied for identification of lithogenic and pedogenic iron oxides in topsoils from Bulgaria [PDF]

GeoStudies
Identification of magnetic minerals, which determine the magnetic properties of natural rocks, sediments and soils, is of crucial importance for any further interpretation of their magnetic signature in environmental or paleogeographical context.

Insights on Lightning‐Induced Remanent Magnetization From High‐Current Impulse Experiments

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Lightning strikes generate intense transient magnetic fields capable of inducing strong and complex remanent magnetizations in rocks, potentially overprinting their original paleomagnetic record. To investigate the mechanisms and outcomes of lightning‐induced remanent magnetization, we conducted controlled high‐current impulse experiments on ...
