Thickness‐Dependent Skyrmion Evolution in Fe3GeTe2 During Magnetization Reversal
Thickness‐ and field‐dependent magnetic domain behavior in 2D van der Waals Fe3GeTe2 is studied using Lorentz TEM and micromagnetic simulations. A patch‐like domain phase evolves from skyrmions during magnetization reversal, and step edges between thickness regions act as pinning sites.

We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

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

In this study, novel resin/cobalt iron oxide magnetic actuation polymer composites (MAPCs) are synthesized and optimized for stereolithography (SLA)‐based 3D printing. Printing parameters are tuned for dimensional accuracy and print quality. Comprehensive physicochemical, mechanical, and magnetic characterization identifies the optimal formulation ...

ABSTRACT Purpose To develop a fat‐water separation approach that corrects bipolar readout gradient‐induced effects without additional scans and is compatible with any fat‐water separation method. Theory and Methods The proposed approach combines joint fat‐water separation of the odd and even echoes of a bipolar multi‐echo gradient echo acquisition with

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...

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