    Pré-requis :

Quantum Mechanics, Basics of Solid State Physics

    Compétences attestées (transversales, spécifiques) :
Develop knowledge of the origin of magnetism and its applications in technology.
    Programme de l'UE / Thématiques abordées :

The aim of this course is to convey adequate knowledge of magnetism in atoms and solids so that magnetic nanostructures and modern spintronics devices can be understood. Students learn about the different forms of magnetism, their microscopic origin and how magnetism is used and applied in contemporary technology. A key part of the lectures is a presentation by a researcher or a representative of a company working in the field. The Auvergne-Rhône-Alpes region is traditionally strong in the domain of magnetism
