Restoration and Transformation: The Response of Shocked and Oxidized Magnetite to Temperature

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 2, February 2024.
Abstract Large impact craters on Earth are associated with prominent magnetic anomalies, residing in magnetite of the shocked target rocks and impactites. Shock experiments on magnetite suggest that up to 90% of magnetic susceptibility is lost at pressures >5 GPa, but can be partially restored by post‐shock thermal annealing.

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 ...

A Key Contribution for Concrete Durability: Harnessing Force‐Magnetic Coupling for Stress State Detection in Reinforced Concrete Beams

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Over the past 20 years, more than 200 major bridge‐collapsed accidents have occurred during their service life. The durability of reinforced concrete (RC) beams is a serious threat to the safety performance of the structures. To accurately grasp the service performance of RC beams, a four‐point bending loading experiment was conducted on RC rectangular

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.

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.

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 ...

Avalanches in mean-field models and the Barkhausen noise in spin-glasses

, 2010
We obtain a general formula for the distribution of sizes of "static avalanches", or shocks, in generic mean-field glasses with replica-symmetry-breaking saddle points.
