Micromagnetic measurements of ferromagnetic materials: Validation of a 3D numerical model

This work if focused on (nondestructive) micromagnetic measurements for ferromagnetic materials in view of Material Characterization (MC). The interest in micromagnetic measurements arises from their correlation to mechanical properties. It is well known that the microstructure of a material affects both mechanical and magnetic properties, therefore it is possible to infer mechanical properties from micromagnetic measurements. This is very convenient because micromagnetic measurements canbe carried out ina fast, cheap and nondestructive manner, if compared to mechanical measurements. To date, a lot of experimental workhas been carried in the past years but there is still some lack of proper numerical models capable of modelling micromagnetic measurements, especially when considering 3D models.Inthispaperwepresentanexperimentalvalidationofanad-hoc3Dnumericalmodelcapableofmodellingtheresponseinmicromagneticcharacterizationof ferromagnetic materials.
