Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions
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.

Non homogeneity of surface integrity after hard milling of high tempered bearing steel
This paper deals with surface integrity after hard milling of high tempered bearing steel 100Cr6. Surface integrity is expressed in terms of shape deviation as well as Barkhausen noise emission. Furthermore, components of cutting forces are also measured

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 ...

A spring-block model for Barkhausen noise [PDF]
A simple mechanical spring-block model is introduced for studying magnetization phenomena and in particularly the Barkhausen noise. The model captures and reproduces the accepted microscopic picture of domain wall movement and pinning. Computer simulations suggest that this model is able to reproduce the main characteristics of hysteresis loops and ...

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.

Barkhausen noise analysis of thin film ferroelectrics
International audienceThe first direct Barkhausen noise measurement in a ferroelectric thin film is presented. The Barkhausen noise energy loop is reconstructed from the measured Barkhausen noise and is closely related to the classic ferroelectric P vs E

A compact microwave sensing system is proposed based on active Fano resonance utilizing injection‐locked oscillation. The Q‐factor is enhanced from 51 to 115,397, and resonance intensity increases from 19 dB to 68 dB. It achieves a resolution of 10 mg/dL over a 100–400 mg/dL range, showing excellent performance in real‐time in vitro sensing validation.

Standalone Integrated Magnonic Devices
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...
