Self similar Barkhausen noise in magnetic domain wall motion [PDF]

open access: yesPhysical Review Letters, 1996
A model for domain wall motion in ferromagnets is analyzed. Long-range magnetic dipolar interactions are shown to give rise to self-similar dynamics when the external magnetic field is increased adiabatically.

Magnetic Barkhausen noise: A simulation tool [PDF]

open access: yesAIP Advances, 2021
Non-destructive magnetic controls are increasing in the industrial field. In this domain, the expectation for simulation tools able to anticipate the magnetic signature, improve the understanding and avoid fastidious and uncertain experimental pre-characterizations is high.

Magnetic Barkhausen Noise Measurements on Rocks

open access: yesTecnura, 2022
Context: The magnetic properties of rocks may reflect the modal abundance, composition, and microstructure of the magnetic grains contained within them, usually in a very small proportion. Magnetic Barkhausen Noise (MBN) is a non-destructive technique applied to magnetic materials, and it is very sensitive to microstructure and residual stresses.

Barkhausen noise emission in soft magnetic bilayer ribbons [PDF]

open access: yesAIP Advances, 2021
Barkhausen noise emission in soft magnetic bilayer ribbons has been investigated. The monolithic amorphous Fe73.5Nb3Si13.5B9Cu1/Fe74.5Nb3Si13.5B9 bilayer system was produced by double-nozzle melt-spinning. It was subsequently used to measure the Barkhausen noise emission in the amorphous state as well as in the annealed state as a function of ...

Barkhausen noise from zigzag domain walls [PDF]

open access: yes, 2006
We investigate the Barkhausen noise in ferromagnetic thin films with zigzag domain walls. We use a cellular automaton model that describes the motion of a zigzag domain wall in an impure ferromagnetic quasi-two dimensional sample with in-plane uniaxial ...

Dynamics of a ferromagnetic domain wall: avalanches, depinning transition and the Barkhausen effect [PDF]

open access: yes, 1998
We study the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium. The avalanche-like motion of the domain walls between pinned configurations produces a noise known as the Barkhausen effect. We discuss

Dynamics of a ferromagnetic domain wall and the Barkhausen effect [PDF]

open access: yes, 1997
We derive an equation of motion for the the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium and we study the associated depinning transition.

Modeling Barkhausen Noise in Magnetic Glasses with Dipole-Dipole Interactions

open access: yes, 2015
Long-ranged dipole-dipole interactions in magnetic glasses give rise to magnetic domains having labyrinthine patterns. Barkhausen Noise is then expected to result from the movement of domain boundaries which is supposed to be modeled by the motion of ...

Magnetic Barkhausen Noise in quenched carburized steels

open access: yesJournal of Physics: Conference Series, 2011
Steels with different carbon content, 0.11%C and 0.48%C were submitted to a heat treatment for carburization in the surface. The samples were analyzed after several types of heat treatment, including quenching for producing martensite. The Magnetic Barkhausen Noise (MBN) is directly related to the microstructure. Samples with lower carbon content, have

Barkhausen noise in soft amorphous magnetic materials under applied stress

open access: yes, 1998
We report experimental measurements of Barkhausen noise on Fe_{64}Co_{21}B_{15} amorphous alloy under tensile stress. We interpret the scaling behavior of the noise distributions in terms of the depinning transition of the domain walls.
