Magnetic materials and systems play a significant role in markets defined as strategic by Europe such as information and communication technologies, mobility, health and energy. Among these, magnetic nanomaterials represent an important challenge both by the wealth of new effects produced and by technological gains (energy efficiency, space gain, multifunctionality, etc.). The SONOMA (Sonder the Magnetic Nanomaterials) project proposes an optimisation work of the Centre of Competence in Magnetic Characterisation (CCMAg) of the Jean Lamour Institute, with a specialisation in nanomaterials, with the objective of performance and attractiveness, and with a direct impact on the quality of scientific production and R&D of its trained users, among a public-private community at regional, national and European level. Sonoma consists of three actions: 1) Strengthening of the CCMag with three characterisation tools dedicated to magnetic nanomaterials. 2) Optimisation of the characterisation processes of magnetic nanomaterials for basic research and R&D. 3) Demonstration of acceleration of projects using CCMag. The expected results at the end of the project are successful disruptive research projects, private partners with high socio-economic impact R & D activities, students and trained professionals.
