Engineering Reports, Volume 7, Issue 1, January 2025.Barkhausen noise (BN)‐ and eddy currents (EC)‐based sensor systems were tested to detect deformation‐induced martensite during flow forming of austenitic steel 304L. The results with EC have advantages over those with BN due to the good correlation with reference α′‐martensite measurements and the low influence of factors such as roughness.

A Magnetoelastic Twist on Magnetic Noise: The Connection with Intrinsic Nonlinearities
Advanced Functional Materials, Volume 34, Issue 9, February 26, 2024.Magnetoelastic nonlinearity significantly limits the performance of devices that use ferromagnetic films as sensitive elements. By introducing a comprehensive theory of magnetic noise in sensor systems, previously unrecognized noise sources linked to magnetoelasticity are revealed.

Research on the Orthogonal Fundamental Mode Fluxgate Sensor Circuit
IEEE Access, 2020 Currently, magnetic fluxgate circuits used for magnetic field measurements mostly adopt parallel excitation second harmonic generation. The magnetic fluxgate developed by this method cannot possess both low noise and high bandwidth at the same time.

Hysteresis, Avalanches, and Barkhausen Noise
, 1997 Hysteresis, the lag between the force and the response, is often associated with noisy, jerky motion which have recently been called ``avalanches''. The interesting question is why the avalanches come in such a variety of sizes: naively one would expect either all small events or one large one.

FRACTAL DIMENSION ANALYSIS OF THE BARKHAUSEN NOISE IN Fe-Si AND PERMALLOY
, 1988 Nonlinear response of the magnetization respect to slowly changing magnetic field gives random noise, i.e., the Barkhausen noise, which is measured on Fe-Si and permalloy.

Application of flaw detection methods for detection of fatigue processes in low-alloyed steel [PDF]
Transport Problems, 2007 The paper presents the investigations conducted in the Fraunhofer Institute (IZFP Saarbrücken) by use of a BEMI microscope (BEMI= Barkhausenrausch- und Wirbelstrom-Mikroskopie or Barkhausen Noise and Eddy Current Microscopy). The ability to detect cyclic

Influence of temperature on Barkhausen noise in Co a Gd [PDF]
The present paper deals with Barkhausen noise emission in Gd. Barkhausen noise emission was investigated in the temperature range mainly below the Gd Curie temperature when the spontaneous magnetization in Gd occurs.

Magnetization fluctuations and magnetic after-effect probed via the anomalous Hall effect
Physical Review ResearchTaking advantage of the anomalous Hall effect, we electrically probe low-frequency magnetization fluctuations at room temperature in a thin ferromagnetic Pt/Co/AlO_{x} layer stack with perpendicular magnetic anisotropy. We observe a strong enhancement of
