2 CFU – Franca Albertini, Massimo SolziThese lectures provide an overview of the basic properties of magnetically ordered solid materials and their explanation in atomic terms. In addition, the effects of fundamental interactions on the magnetic phenomenology at the different length scales will be highlighted. The students will become familiar with the main concepts, effects and definitions, which constitute the necessary basis for understanding the current topics of modern magnetism. These concepts will be adopted for explaining the magnetic and multi-functional properties of some emerging classes of magnetic materials in frontier applications in the fields of energy, biomedicine and information technology.
