Development of functional magnetic materials for energy harvesting at the micro-scale

par Erika Fontana

Projet de thèse en Physique des materiaux

Sous la direction de Nora Dempsey et de Thibaut Devillers.

Thèses en préparation à Grenoble Alpes , dans le cadre de École doctorale physique (Grenoble) , en partenariat avec Institut Néel (laboratoire) depuis le 15-11-2018 .


  • Résumé

    Two material types will be studied, hard magnetic materials and magnetic phase change materials. In the case of hard magnetic materials, micro-magnets will be produced using both film-based and powder-based approaches, the former for magnets of size 5-50 µm, the latter for magnets of size 50-500 µm. Complex powder-based magnets will be made by combining 3D printing with 3D magnetic patterning. In the case of magnetic phase change materials, Gd and LaFeSi films will be developed. The challenge here will be to produce thick films with suitable magnetic and mechanical properties. Both material types will be integrated into energy harvester prototypes, in the framework of an ANR project. This part of the thesis will be done in collaboration with partner-labs specialized in the modelling of thermomagnetic power generation, and the design and fabrication of prototype microsystems.
