Magnetic Barkhausen Noise Measurements on Rocks
Tecnura, 2022 Context: The magnetic properties of rocks may reflect the modal abundance, composition, and microstructure of the magnetic grains contained within them, usually in a very small proportion. Magnetic Barkhausen Noise (MBN) is a non-destructive technique applied to magnetic materials, and it is very sensitive to microstructure and residual stresses.

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.

Feasibility of Assessing the Tempering Condition of High-Strength Steel using Barkhausen Noise [PDF]
Problemy MechatronikiThis study evaluates whether the hardness of 42CrMo4 high-strength steel can be determined using the Magnetic Barkhausen Noise method. Steel specimens were quenched and then tempered at different temperatures. Barkhausen noise measurements were performed,

Experimental Evidence for a Metal-Related Function of a Cyanobactin. [PDF]
Angew Chem Int Ed EnglCyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.

Magnetic Hysteresis and Barkausen Noise in Plastically Deformed Steel Sheets
Metals, 2017 The magnetic properties of steels are affected by plastic deformation, because the domain wall processes magnetoelastically interact with the dislocations and the residual stresses.

Magnetic Signatures and Magnetization Mechanisms for Grinding Burns Detection and Evaluation
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.
