Barkhausen Noise from Precessional Domain Wall Motion [PDF]

, 2019
The jerky dynamics of domain walls driven by applied magnetic fields in disordered ferromagnets - the Barkhausen effect - is a paradigmatic example of crackling noise. We study Barkhausen noise in disordered Pt/Co/Pt thin films due to precessional motion

Integrated Field‐Free SOT Domain‐Wall Synapses and MTJ Stochastic Neurons for Hardware Boltzmann Machines

Advanced Functional Materials, Volume 36, Issue 61, 30 July 2026.
Field‐free spin‐orbit torque domain‐wall synapses integrated with stochastic MTJ neurons enable compact hardware Boltzmann machines. Leveraging intrinsic stochasticity and multi‐level conductance, the system achieves efficient probabilistic learning with high accuracy, demonstrating a scalable spintronic platform for energy‐efficient edge AI.

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.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions

Advanced Functional Materials, Volume 36, Issue 41, 21 May 2026.
Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Composite‐Field Annealing Enables Superior High‐Temperature Noise Stability in Fluxgate Sensors With Co‐Rich Amorphous Microwires

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Partial Discharge Detection and Localization in Power Transformers Using an Integrated Fiber‐Optic Acoustic Monitoring Framework

Journal of Sensors, Volume 2026, Issue 1, 2026.
This paper presents the methodology and design of an online partial discharge (PD) monitoring system aimed at enhancing the reliability of power transformers through the use of fiber optic acoustic sensors. PD is a critical indicator of insulation degradation in transformers, which can lead to catastrophic failures if not monitored effectively.
