Demagnetization investigation of a partitioned rotor flux switching machine with hybrid permanent magnet

open access: yesAIP Advances, 2017
In this paper, the partitioned rotor flux switching permanent magnet machine with ferrite permanent magnet is proposed. By the adoption of the partitioned rotor configuration, the stator flux leakage is eliminated and the permanent magnet utilization is ...

Demagnetization signatures of lunar impact craters

open access: yes, 2002
We investigate the crustal magnetic signatures of lunar craters using Lunar Prospector (LP) electron reflectometer data. Craters of all ages often have associated magnetic lows, showing that crustal fields were present even in pre-Nectarian times (≳3.9 ...

XAHRM‐Lab First Results and πXRF First View of UFe4Al8 and UFe10Si2

open access: yesX-Ray Spectrometry, Volume 55, Issue 4, Page 597-604, July/August 2026.
ABSTRACT Following the installation of the Laboratory for the Characterization and Speciation of Aerosols (LCEA) in 2008, and the confirmation of High Resolution Energy Dispersive Spectrometry (HiREDS) as a much promising development for X‐ray Emission Spectrometry in general and Particle Induced X‐ray Emission (PIXE) in particular, the installation of

Three-stage ultrafast demagnetization dynamics in a monolayer ferromagnet

open access: yesNature Communications
Intense laser pulses can be used to demagnetize a magnetic material on an extremely short timescale. While this ultrafast demagnetization offers the potential for new magneto-optical devices, it poses challenges in capturing coupled spin-electron and ...

Theory of laser-induced demagnetization at high temperatures

open access: yes, 2011
Laser-induced demagnetization is theoretically studied by explicitly taking into account interactions among electrons, spins, and lattice. Assuming that the demagnetization processes take place during the thermalization of the subsystems, the temperature

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Paleomagnetic Evidence of Internal Rotation in the Eastern Qiangtang and Its Relation to Distributed Strike‐Slip Faulting in the Southeastern Tibetan Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The southeastern Tibetan Plateau has undergone complex deformation due to the India‐Eurasia collision. Although late‐stage internal rotations are documented in the Lanping‐Simao Terrane to the south, it remains unclear whether similar processes have affected the north.

Demagnetization Procedure for the MBN Magnets

open access: yes, 2002
Results from demagnetization tests of an MBN magnet are reported here. Following a "texbook" demagnetization procedure where alternating polarity current settings from saturation (1500A) down to 1% of this (15A) are applied, a remnant field of the order ...

Late Carboniferous Paleomagnetism From North Qiangtang Block Reveals a Multibranched Paleo‐Tethys Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The North Qiangtang Block occupies a pivotal position within the eastern Tethyan realm, and its paleogeographic reconstruction is critical for constraining Tethyan geometry and evolution. However, its Late Paleozoic paleogeography and Paleo‐Tethyan Ocean–continent configuration remain controversial due to limited reliable age‐constrained ...

Ultrafast spin transport as key to femtosecond demagnetization

open access: yes, 2013
Irradiating a ferromagnet with a femtosecond laser pulse is known to induce an ultrafast demagnetization within a few hundred femtoseconds. Here we demonstrate that direct laser irradiation is in fact not essential for ultrafast demagnetization, and that
