The goal of this project is to demonstrate thermo-magnetic power generation using giant magneto-caloric materials as working substance to convert low grade waste heat into electrical energy (collaboration with SATIE et C2N de l’Université Paris-Saclay and Louis Néel Institute in Grenoble). We shall show that magneto-caloric materials based on thermo-magnetic power generation could become a leading technology for a new generation of efficient highspower density micro-generators oriented towards applications to data-centers, microelectromechanical systems and small autonomous systems. This will be achieved through the design and assembly of an efficient high-power density thermo-magnetic power generation device. At INSP we will be concerned by the production and the characterization of MCM film with optimized properties.
Caption: Improvement of the magnetocaloric properties of layers of Gd (thickness 3 microns) deposited on Si. Variation of the magnetic entropy around room temperature. It can be seen that growth at 550° improves the magnetocaloric power. Gd layers will be used in devices for thermo-magnetic generation (Doan Nguyen Ba, et al. AIP Advances 2020).
