Continuous Scanning Technique with Barkhausen Magnetic Noise for Carbon Steel Sheets [PDF]
This work studies the application of a Non-Destructive Inspection Technique (NDIT), based on the Magnetic Barkhausen Noise (MBN), for the detection of non-homogeneous regions in carbon steel plates.

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

Magnetic Barkhausen Noise Measurements on Rocks
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.

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

An auxiliary device for internal pipeline stress detection based on Barkhausen effect
For the requirements of integrated internal detection of the pipeline stress concentration and metal damage, the internal stress detection technology based on continuous Barkhausen effect was studied, and an auxiliary device for internal stress detection

Barkhausen noise from formation of 360^{∘} domain walls in disordered permalloy thin films
Barkhausen noise in disordered ferromagnets is typically understood to originate primarily from jerky field-driven motion of domain walls. We study the magnetization reversal process in disordered permalloy thin films using micromagnetic simulations and ...

Case Depth Prediction of Nitrided Samples with Barkhausen Noise Measurement
Nitriding is a heat treatment process that is commonly used to enhance the surface properties of ferrous components. Traditional quality control uses sacrificial pieces that are destructively evaluated.

Influence of Components Bending on the Consecutive Plasma Nitridation and Barkhausen Noise Emission
This paper deals with the non destructive evaluation of components after the plasma nitridation via the Barkhausen noise techniques. Effect of different surface states before the plasma nitriding is studied via the non destructive Barkhausen noise ...
