Stress-Driven Magnetic Barkhausen Noise Generation in FeCo Magnetostrictive Alloy

Takahiro Yamazaki et al.

Summary: This study provides an in-depth understanding of the responsiveness of stress-driven magnetic Barkhausen noise (MBN) to external stress. It demonstrates that ferromagnetic materials with a high magnetostriction constant can be used to develop a high-sensitivity force sensor. By changing the stress rate level, the relationship between the stress rate and the root-mean-square (rms) value of MBN output voltages is determined, showing high sensitivity and acceptable linearity. This research will aid in the development of novel applications for high-sensitivity force sensors.

Multiscale modelling of the magnetic Barkhausen noise energy cycles

P. Fagan et al.

Summary: The article discusses the application of magnetic Barkhausen noise (MBN) control in materials characterization and non-destructive testing, as well as the method and results of studying hysteresis cycles through MBN energy. The study proposes a simulation method combining a multiscale model and the Jiles-Atherton theory to accurately simulate MBNenergy hysteresis cycles, showing promising results for a comprehensive simulation tool dedicated to MBN.

An Integrated Model of Magnetic Hysteresis, the Magnetomechanical Effect, and the Barkhausen Effect

David C. Jiles et al.

Summary: This article reviews the ferromagnetic hysteresis, magnetomechanical, and Barkhausen properties of magnetic materials and presents an integrated model to describe these effects and the underlying mechanisms that cause these effects. Several models are used to describe the magnetic hysteresis of ferromagnetic materials, including the Jiles-Atherton hysteresis model. These models have been extended to include the magnetomechanical effect and the Barkhausen effect.
