Micromagnetic approaches for microstructure analysis and capability assessment

The non-destructive testing methods based on Barkhausen noise and eddy current are very versatile and flexible. The application of these techniques in materials and components testing, production processes and new fields of utilization has been an aim of the authors for almost one decade of research. This paper provides an overview of the history of micromagnetic testing, the fundamentals of micromagnetism in ferromagnetic materials and allows an insight into several ongoing research projects in the wide-ranging fields of materials characterization and production engineering.
