Monitoring of Surface Damage in Rails After Long Term Cyclic Loading
Communications, 2017 This paper reports about possible concept in which surface damage of the rail after long tem cyclic loading can be executed. This study employs non destructive magnetic Barkhausen noise as a promising technique which exhibits very good sensitivity ...

Crackling Noise, Power Spectra and Disorder Induced Critical Scaling
, 2001 Crackling noise is observed in many disordered non-equilibrium systems in response to slowly changing external conditions. Examples range from Barkhausen noise in magnets to acoustic emission in martensites to earthquakes.

Small Structures, Volume 6, Issue 11, November 2025.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.

Evaluation of the Residual Stress State of 42crmo4 Steel Sheets in a Production Line [PDF]
Materials Research, 2016 The residual stress state of a mechanical component is an important factor in its production planning and in estimates of its lifecycle since it can be responsible for geometric distortions and degradation of fatigue properties.

Standalone Integrated Magnonic Devices
Advanced Materials, Volume 37, Issue 40, October 9, 2025.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 ...

Advanced Materials Technologies, Volume 10, Issue 18, September 18, 2025.A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.

Finite driving rates in interface models of Barkhausen noise
, 2001 We consider a single-interface model for the description of Barkhausen noise in soft ferromagnetic materials. Previously, the model had been used only in the adiabatic regime of infinitely slow field ramping. We introduce finite driving rates and analyze
