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

, 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.

Barkhausen noise in soft amorphous magnetic materials under applied stress

, 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.

A spring-block model for Barkhausen noise

, 2004
A simple mechanical spring-block model is introduced for studying magnetization phenomena and in particularly the Barkhausen noise. The model captures and reproduces the accepted microscopic picture of domain wall movement and pinning.

Modeling Barkhausen Noise in Magnetic Glasses with Dipole-Dipole Interactions

, 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 ...

On the power spectrum of magnetization noise [PDF]

, 2001
Understanding the power spectrum of the magnetization noise is a long standing problem. While earlier work considered superposition of 'elementary' jumps, without reference to the underlying physics, recent approaches relate the properties of the noise ...

Magnetic Hysteresis and Barkausen Noise in Plastically Deformed Steel Sheets

Metals, 2017
The magnetic properties of steels are affected by plastic deformation, because the domain wall processes magnetoelastically interact with the dislocations and the residual stresses.

Signature of effective mass in crackling noise asymmetry

, 2005
Crackling noise is a common feature in many dynamic systems [1-9], the most familiar instance of which is the sound made by a sheet of paper when crumpled into a ball.

Grinding burn classification with surface Barkhausen noise measurements

Research and Review Journal of Nondestructive Testing, 2023
Industrial Barkhausen noise (BN) measurements are commonly utilized for final quality control after machining operations such as grinding to point out grinding burns.

Case depth in SAE 1020 steel using barkhausen noise [PDF]

Materials Research, 2013
The most widely used thermochemical process for surface hardening of steels is case hardening. Using several different heat treatments, martensitic surface layers were formed on SAE 1020 steel into which carbon had been diffused.
