Operational Parameters for Sub-Nano Tesla Field Resolution of PHMR Sensors in Harsh Environments
The resolution of planar-Hall magnetoresistive (PHMR) sensors was investigated in the frequency range from 0.5 Hz to 200 Hz in terms of its sensitivity, average noise level, and detectivity.

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

Domain size effects in Barkhausen noise
The possible existence of self-organized criticality in Barkhausen noise is investigated theoretically through a single interface model, and experimentally from measurements in amorphous magnetostrictive ribbon Metglas 2605TCA under stress.

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

Barkhausen noise (BN)‐ and eddy currents (EC)‐based sensor systems were tested to detect deformation‐induced martensite during flow forming of austenitic steel 304L. The results with EC have advantages over those with BN due to the good correlation with reference α′‐martensite measurements and the low influence of factors such as roughness.
