Barkhausen-type noise in the resistance of antiferromagnetic Cr thin films

, 2012
We present an experimental study of the changes generated on the electrical resistance $R(T)$ of epitaxial Cr thin films by the transformation of quantized spin density wave domains as the temperature is changed. A characteristic resistance noise appears

Barkhausen Noise Assessment of the Surface Conditions Due to Deep Hole Drilling and Their Influence on the Fatigue Behaviour of AISI 4140

Metals, 2018
In many technical fields, high-strength steels like AISI 4140 are commonly used for highly dynamically loaded parts. Increasing demands on weight, performance and efficiency of the automotive industry lead to increasing demands on material properties ...

Correlations of triggering noise in driven magnetic clusters

, 2000
We show that the temporal fluctuations $\Delta H(t)$ of the threshold driving field $H(t)$, which triggers an avalanche in slowly driven disordered ferromagnets with many domains, exhibit long-range correlations in space and time.

Thermodynamics as a nonequilibrium path integral

, 2010
Thermodynamics is a well developed tool to study systems in equilibrium but no such general framework is available for non-equilibrium processes. Only hope for a quantitative description is to fall back upon the equilibrium language as often done in ...

Fatigue Assessment of Quenched and Tempered Steels Based on Temperature and Micro-Magnetic Measurements

Research and Review Journal of Nondestructive Testing
Magnetic Barkhausen Noise measurements are advantageous for the fatigue characterisation of ferromagnetic materials since they can provide information regarding microstructure, residual stresses, hardness and the presence of microstructural defects. The

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.
