The proposed Ph.D. aims to contribute in the use of spectrum measurements for the characterisation of magnetic materials, notably steels. Accurate MBN measurements obtained from different microstructures using a dedicated setup (developed in the context of the Ph.D. work) will be analysed and compared with theoretical simulations based on tools previously developed by the host institute in order to

• Validate and fine-tune the models


• Examine the classification of the considered microstructures in universality classes


• Study the effect of the microstructure (grain size, dislocations) to the spectral features

Starting from well-known model materials (FeSi and FeCo), for which a great amount of published results exist and hence can be used as reference, the study will be then focused on some important industrial steel grades like the interstitial-free (IF) and low-carbon (LC) steels.

The proposed Ph.D. thesis will be jointly directed and supervised by the French atomic and alternative energies commission (CEA, Commissariat à l'énergie atomique et aux énergies alternatives) and the CEIT Technological Centre in Spain (CEA-LIST en Gif-sur-Yvette (near Paris) France) and CEIT in San Sebastian). The main part of the work will be hosted at the CEA research centre at Saclay, France with a couple of monthly stays at the CEIT institute in San Sebastian, Spain.
