Débutée en octobre 1998This work was conducted within the framework of a CNRS program, called the ‘materials program', and specially in the project #154 : ‘nanostructured soft magnetic materials. This study consist in elaboration of magnetic composites from milled commercial ferrite and iron or permalloy nanopowders, and their characterisation. The aim was to take advantage of the resistivity of the spinel ferrite on the one hand, of the strong magnetisation and soft magnetic properties of metallic nanoparticles on the other hand. The dispersion of metallic particles is realised by comilling. First, some basis of the magnetic theory are recalled (chapter 1). Then the peculiar physic and magnetic properties of nanometric materials are presen...
