Experimental Consideration of Conditions for Measuring Residual Stresses of Rails Using Magnetic Barkhausen Noise Method. [PDF]
Materials (Basel), 2021 Residual stress, a factor affecting the fatigue and fracture characteristics of rails, is formed during the processes of fabrication and heat treatment, and is also generated by vertical loads on wheels due to the weight of vehicles.

Self similar Barkhausen noise in magnetic domain wall motion [PDF]
Physical Review Letters, 1996 A model for domain wall motion in ferromagnets is analyzed. Long-range magnetic dipolar interactions are shown to give rise to self-similar dynamics when the external magnetic field is increased adiabatically.

Magnetic Signatures and Magnetization Mechanisms for Grinding Burns Detection and Evaluation [PDF]
Sensors, 2023 Grinding thermal damages, commonly called grinding burns occur when the grinding energy generates too much heat. Grinding burns modify the local hardness and can be a source of internal stress.

Development and Degradation Study of PLA-Based Medical Implant Markers for Magnetic Particle Imaging. [PDF]
Macromol BiosciNonpermanent marking technology is needed for medical instruments for accurate visualization in magnetic particle imaging. In this work, markers based on superparamagnetic iron‐oxide nanoparticles (SPIONs) and polylactic acid (PLA) are developed and investigated over a time frame of 28 days.
