« Qu’es chabat ». Une expérience de la disparition entre présence et rémanence. Situation de l’occitan dans le nord limousin

Lengas, 2013
In this paper, we attempt to analyze the situation of Limousin Occitan, or rather what remains of it, through a series of cases encountered during a campaign of documentary filmmaking in Occitan.

Diffusion temperature dependent microstructure and magnetic properties of TbHx grain boundary diffused Nd–Fe–B magnets

AIP Advances, 2021
Commercial N50 sintered Nd–Fe–B magnets were grain boundary diffusion (GBD) processed with TbHx powders. The diffusion temperature and time dependent microstructure and magnetic properties of the GBD processed magnets were investigated.

Experimental Study on Magnetization and Demagnetization Characteristics of X70 Steel Pipe

Shiyou jixie, 2022
The remanence in the pipe not only affects the detection accuracy, but also accelerates the corrosion rate in the pipe. In order to study the magnetization and demagnetization characteristics of X70 steel pipe, based on the analysis of material ...

Magnetic Properties of Epitaxial and Polycrystalline Fe/Si Multilayers

, 1995
Fe/Si multilayers with antiferromagnetic interlayer coupling have been grown via ion-beam sputtering on both glass and single-crystal substrates. High-angle x-ray diffraction measurements show that both sets of films have narrow Fe peaks, implying a ...

Trapdoor Viscous Remanent Magnetization

Geophysical Research Letters, 2023
AbstractViscous remanent magnetization (VRM) in multidomain (MD) particles has many puzzling properties that deviate from the current VRM theory, based on Néel's single‐domain model of magnetic particles with an almost symmetric double‐well potential.

Magnetic remanence of Josephson junction arrays

, 1999
In this work we study the magnetic remanence exhibited by Josephson junction arrays in response to an excitation with an AC magnetic field. The effect, predicted by numerical simulations to occur in a range of temperatures, is clearly seen in our ...
