Generic role of the Dzyaloshinskii–Moriya interaction in nanocrystalline ferromagnets

open access: yesNew Journal of Physics, 2023
Motivated by recent experimental polarized neutron results, we present a numerical micromagnetic study of the interfacial (intergrain) Dzyaloshinskii–Moriya interaction (DMI) in nanocrystalline terbium.

Instability of vortex-antivortex interface in optimally-doped Ba(Fe_{1-x}Co_{x})_{2}As_{2}

open access: yes, 2011
We explore the flux front patterns during virgin penetration and after remagnetization in the iron-based superconductor Ba(Fe_{1-x}Co_{x})_{2}As_{2}.

Multiply remagnetized Silurian carbonate sequence in Estonia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2008
Palaeomagnetic studies were carried out on Silurian sedimentary rocks of Estonia. The studied sequence (126 samples from 4 localities) is composed of Silurian lime- and dolostones of Llandovery and Wenlock age (444–423 Ma).

Controlled domain wall pinning in ferromagnetic nanowire by nanoparticles stray fields

open access: yes, 2015
We report the results of experimental investigations of controlled domain wall (DW) pinning in a ferromagnetic nanowire (NW) by stray fields of two uniformly magnetized bistable ferromagnetic nanoparticles (NPs) placed on either side of the NW and ...

The magnetic reversal in dot arrays recognized by the self-organized adaptive neural network

open access: yes, 2003
The remagnetization dynamics of monolayer dot array superlattice XY 2-D spin model with dipole-dipole interactions is simulated. Within the proposed model of array, the square dots are described by the spatially modulated exchange-couplings.

Remagnetization and fluids

open access: yesEos, Transactions American Geophysical Union, 1992
Remagnetization, the acquisition of a secondary magnetization, is accepted as a widespread phenomenon in sedimentary rocks. The recognition that many sedimentary rocks were partially or completely remagnetized long after deposition has not only led to a reevaluation of the paleomagnetic data base [for example, Van der Voo, 1989], but has also led to a ...

Untangling inconsistent magnetic polarity records through an integrated rock magnetic analysis: A case study on Neogene sections in East Timor

open access: yesGeochemistry, Geophysics, Geosystems, 2014
Inconsistent polarity patterns in sediments are a common problem in magnetostratigraphic and paleomagnetic research. Multiple magnetic mineral generations result in such remanence “haystacks.” Here we test whether end‐member modeling of isothermal ...

Testing the use of viscous remanent magnetisation to date flood events [PDF]

open access: yes, 2015
© 2015 Muxworthy, Williams and Heslop. Using erratics associated with large flood events, this paper assesses whether their viscous remanent magnetisation (VRM) can be used to date the flood events.

A Paleomagnetic Inspection of the Paleocene-Eocene Thermal Maximum (PETM) in the Southern Pyrenees

open access: yesFrontiers in Earth Science, 2018
Magnetic properties of rocks can be useful for determining paleoenvironmental changes. A dramatic climate change that occurred in the Paleocene-Eocene Thermal Maximum (PETM) modified the environment and, hence, the magnetic properties recorded in the ...
