Magnetic parameters as proxies for anthropogenic pollution in water reservoir sediments from Mexico: an interdisciplinary approach [PDF]

, 2020
We assess the element pollution level of water reservoir sediments using environmental magnetism techniques as a novel approach. Although “La Purísima” Water Reservoir is an important source for multiple activities (e.g.

Erroneous fold tests as an artifact of alteration chemical remanent magnetization [PDF]

Journal of Geophysical Research: Solid Earth, 2002
Several studies have shown that an alteration chemical remanent magnetization (CRM) may have a direction intermediate between that of the remanence of the parent phase and the field during remagnetization. In a fold a surviving natural remanent magnetization (NRM) is exposed at varying angles to the remagnetizing field, giving rise to varying degree of

Self-reversal of chemical remanent magnetization: a palaeomagnetic example [PDF]

Geophysical Journal International, 1987
Summary An anomalous region with complicated thermal demagnetization characteristics has been observed in Siluro-Devonian andesites from the contact aureole of a 6.2 m wide Tertiary dyke in the Mull dyke swarm, Scotland. Outside this anomalous region, rocks from the contact aureole carry a simple two component remanence.

Plasma-assisted synthesis and study of structural and magnetic properties of Fe/C core shell

AIP Advances, 2017
Pure and carbon-encapsulated iron nanoparticles with an average diameter of 25 nm were synthesized by using the DC plasma arc discharge method. Fe core nanoparticles were encapsulated with carbon layer, which is acting as protection layer against both ...

Reductive chemical demagnetization: a new approach to magnetic cleaning and a case study of reef limestones

Earth, Planets and Space, 2018
Chemical demagnetization is not preferred as a demagnetizing method in paleomagnetism because strong acids are cumbersome to handle and require considerable time compared to alternating field and thermal demagnetizations.

The effect of low‐temperature hydrothermal alteration on the remanent magnetization of synthetic titanomagnetites: A case for acquisition of chemical remanent magnetization [PDF]

Journal of Geophysical Research: Solid Earth, 1991
The effect of hydrothermal alteration on the thermoremanent magnetization (TRM) of synthetic titanomagnetite (TM40: Fe2.6Ti0.4O4) has been studied, to simulate the alteration that occurs in the oceanic crust. Pseudo‐single‐domain titanomagnetite grains, similar in size to those often found in oceanic basalts, were dispersed in a permeable but rigid ...

Hedgehog Spin-texture and Berry's Phase tuning in a Magnetic Topological Insulator

, 2012
Understanding and control of spin degrees of freedom on the surfaces of topological materials are key to future applications as well as for realizing novel physics such as the axion electrodynamics associated with time-reversal (TR) symmetry breaking on ...

Sedimentary Iron Cycling and the Origin and Preservation of Magnetization in Platform Carbonate Muds, Andros Island, Bahamas [PDF]

, 2007
Carbonate muds deposited on continental shelves are abundant and well-preserved throughout the geologic record because shelf strata are difficult to subduct and peritidal carbonate units often form thick, rheologically strong units that resist ...

The Effect of Early Diagenesis in Methanic Sediments on Sedimentary Magnetic Properties: Case Study From the SE Mediterranean Continental Shelf

Frontiers in Earth Science, 2020
Microbial respiration in marine sediment can affect the magnetic properties of the sediment through a complicated interplay between reductive dissolution and authigenic precipitation of iron-bearing magnetic minerals.
