Abstract
This lecture is aimed at providing an overview of the main phenomena which determine the magnetism of matter and the properties of magnetic materials. The main interactions involved are qualitatively described in the first section. The models at the basis of the interpretation of the magnetic properties of materials are presented in the second section. The subtle interplay between various interactions may lead to a variety of different behaviours which are described in Sect. 3. The influence of dipolar interactions on the magnetic properties at the macroscopic scale is described in Sec. 4, and the concept of coercivity, important for applications is introduced in the last part of this section. The last section deals with thin films and small particles, systems in which the reduction in material dimension has a drastic influence on the observed properties.
