Unexpected Magnetic Behavior of Natural Hematite‐Bearing Rocks at Low Temperatures

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Hematite is a commonly occurring magnetic mineral in nature that has numerous scientific and technological applications. A characteristic property of hematite is a low‐temperature spin‐flop transition called the Morin transition.

Paleomagnetism of the Upper Cretaceous Daijiaping Formation red beds in the Chaling Basin, Hunan Province, China

open access: yes地质科技通报, 2023
Objective Red beds are widely used in palaeomagnetic studies as they can carry stable natural remanence. Most previous studies on red beds have mainly focused on lacustrine-fluvial facies, with limited targeting the aeolian red beds.

Anisotropy of Full and Partial Anhysteretic Remanence Across Different Rock Types: 2—Coercivity Dependence of Remanence Anisotropy

open access: yesTectonics, 2020
Magnetic fabrics are powerful tools in structural geology and tectonic studies, because they provide a fast and efficient measurement of mineral alignment, which helps interpret a rock's (de)formation history.

High thermal stability of anti-ferromagnetic coupled molecules with FeCo layers

open access: yesAIP Advances, 2021
We propose the optimization of the magnetic remanence and the thermal stability of Mn phthalocyanine coupled with a ferromagnetic substrate, by exploiting interlayer exchange coupling within an advanced organic spin interface architecture, constituted by

Distribution of magnetic remanence carriers in the human brain

open access: yesScientific Reports, 2018
That the human brain contains magnetite is well established; however, its spatial distribution in the brain has remained unknown. We present room temperature, remanent magnetization measurements on 822 specimens from seven dissected whole human brains in

A New Tool for Separating the Magnetic Mineralogy of Complex Mineral Assemblages from Low Temperature Magnetic Behavior

open access: yesFrontiers in Earth Science, 2017
One timeless challenge in rock magnetic studies, inclusive of paleomagnetism and environmental magnetism, is decomposing a sample's bulk magnetic behavior into its individual magnetic mineral components.
