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 ...

The Significance of Magnetic Fabrics Preserved in Hydrothermally Altered Rocks

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Anisotropy of Magnetic Susceptibility (AMS) and Anisotropy of Magnetic Remanence (AMR) are critical petrofabric tools for investigating the evolution of volcano‐magmatic, tectonic, and surface process systems. These highly sensitive techniques can distinguish multiple magnetic fabrics within individual samples, crucial in assessing archives of

Surface coating affects behavior of metallic nanoparticles in a biological environment

Beilstein Journal of Nanotechnology, 2016
Silver (AgNPs) and maghemite, i.e., superparamagnetic iron oxide nanoparticles (SPIONs) are promising candidates for new medical applications, which implies the need for strict information regarding their physicochemical characteristics and behavior in a

Magnetic hydrophobic nanocomposites: Silica aerogel/maghemite

Physica B: Condensed Matter, 2012
Magnetic hydrophobic aerogels (MHA) in the form of nanocomposites of silica and maghemite (g-Fe2O3) were prepared by one step sol–gel procedure followed by supercritical solvent extraction. Silica alcogels were obtained from TEOS, MTMS, methanol and H2O, and Fe(III) nitrate as magnetic precursor.

Intensification of Northern Hemisphere Glaciation Triggered the Red Clay to Loess‐Paleosol Shift on the Chinese Loess Plateau 2.7 Million Years Ago

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Widespread aeolian loess‐paleosol and red clay sediments on the Chinese Loess Plateau (CLP) provide a globally unique terrestrial archive of Neogene–Quaternary climate. However, the timing and associated mechanisms of red clay to loess‐paleosol shift remain debated.

Unraveling the Enrichment Mechanisms of Rare Earth Elements in Deep‐Sea Sediments: An Environmental Magnetic Perspective

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.

The Submm and mm Excess of the SMC: Magnetic Dipole Emission from Magnetic Nanoparticles?

, 2012
The Small Magellanic Cloud (SMC) has surprisingly strong submm and mm-wavelength emission that is inconsistent with standard dust models, including those with emission from spinning dust.

Size and polydispersity effect on the magnetization of densely packed magnetic nanoparticles

, 2012
The magnetic properties of densely packed magnetic nanoparticles (MNP) assemblies are investigated from Monte Carlo simulations. The case of iron oxide nanoparticles is considered as a typical example of MNP.

Structural identification of cubic iron-oxide nanocrystal mixtures: X-ray powder diffraction versus quasi-kinematic transmission electron microscopy [PDF]

, 2008
Two novel (and proprietary) strategies for the structural identification of a nanocrystal from either a single high-resolution (HR) transmission electron microscopy (TEM) image or a single precession electron diffraction pattern are proposed and their ...
