A Flexible Approach for Fat‐Water Separation With Bipolar Readouts and Correction of Gradient‐Induced Phase and Amplitude Effects

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1462-1477, March 2026.
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

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
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 ...

Comparing Paleointensity Recording Efficiencies of Detrital and Biogenic Magnetite by Deposition Experiments With Synthetic Sediments

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Marine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time. Previous studies have demonstrated that the recording efficiencies of detrital and biogenic magnetite differ.

Magnetic indicators parameters of contamination by heavy metals in soils of Almendares-Vento basin

Minería y Geología, 2019
In order to verify if the magnetic parameters can be indicators of soil contamination, the relationship between magnetic parameters and the concentration of heavy metals in soil samples from the Almendares-Vento basin was studied.

Archeointensity Database and Geomagnetic Field Reference Curves for South America Over the Past 5 Millennia

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The study of variations in geomagnetic field intensity over time and space is crucial to understand the evolution of the geodynamo and its interactions with the Earth's surface. In this work, we introduce the SAGEOMAG (South America GEOMAGnetic) database, a comprehensive and updated repository of geomagnetic field intensity records derived ...

Distance‐Dependent Stray Field Decay in Magnetically Stable Remanence Carriers: Implications for Magnetic Microscopy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Micropaleomagnetic analysis offers a path to high‐precision reconstructions of ancient magnetic fields from terrestrial and space‐returned samples by inverting the vertical stray field of individual particles to recover their magnetic moments through the use of magnetic microscopes.

Early Solar Wind and Dynamo Magnetic Field Topology Predictions for (16) Psyche and Other Asteroids

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche is a metal‐rich body that might record an ancient coherent magnetization if some relict crust or mantle is preserved. Herein, we use magnetohydrodynamic simulations to predict (16) Psyche's field topology for several distinct pathways: (i) an early solar wind‐induced magnetization imparted after a larger body was impacted,

Proposal of a novel APPLE‐KNOT undulator by selecting the KNOT field as the dominant magnetic field

Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 289-297, March 2026.
The degradation of circular polarization state in conventional APPLE‐KNOT undulators has been noted. To overcome this limitation, we propose a novel APPLE‐KNOT undulator design which utilizes the KNOT magnetic field as the dominant component.The APPLE‐KNOT undulator forms composite magnetic fields by superimposing an APPLE field and a KNOT field with ...
