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.

Magnetization reversal in kagome artificial spin ice studied by first-order reversal curves [PDF]

, 2017
Magnetization reversal of interconnected kagome artificial spin ice was studied by the first-order reversal curve (FORC) technique based on the magneto-optical Kerr effect and magnetoresistance measurements. The magnetization reversal exhibits a distinct

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Fingerprinting Inhomogeneities in Recording Media Using the First-Order Reversal Curve Method [PDF]

, 2011
Understanding how interactions within magnetic systems affect the reversal process is critical to the development of magneticrecording media. Using the first-order reversal curve (FORC) method we demonstrate an ability to map out and uniquely ...

First-order reversal curve diagrams: a new tool for characterizing the magnetic properties of natural samples

, 2000
Paleomagnetic and environmental magnetic studies are commonly conducted on samples containing mixtures of magnetic minerals and/or grain sizes. Major hysteresis loops are routinely used to provide information about variations in magnetic mineralogy and ...
