Magnetic Fabric: A Geophysical Approach for Identifying China's Neolithic Rammed Earth

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Accurate identification of rammed‐earth remains is essential for understanding early social complexity in Neolithic China. However, scientific methods for identifying rammed‐earth materials in Chinese prehistoric archeology remain limited, and identification still rely largely on field observations.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Accelerated Ordering of Cu Atoms and Synergistic Dual Anisotropy for Enhanced High‐Frequency Soft Magnetic Properties in Fe‐Based Alloys

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The inherent trade‐off between high saturation induction (Bs) and low core loss in soft magnetic materials presents a challenge in the development of high‐frequency power electronics. Here, a processing approach that combines accelerated Cu ordering with dual magnetic anisotropy control in high‐Bs Fe‐based nanostructured cores is examined ...

Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...

Fe‐Based Nanocrystalline Magnetic Shielding Cylinder with Subfemtotesla‐Level Magnetic Noise

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Shields with low magnetic noise are achieved by integrating Fe‐based nanocrystalline magnetic shielding cylinders into shielding systems based on μ‐metal. Benefiting from high permeability and low loss factor, Fe‐based nanocrystalline magnetic shielding cylinders effectively suppress magnetic noise. Notably, the magnetic shielding cylinder with the ten‐
