INTRINSIC AND DOMAIN MAGNETISM IN NANOCRYSTALLINE MATERIALS

Magnetic properties of individual nanoparticles, their ensembles, nano composites and nanocrystalline homogeneous ferromagnets are reviewed. Size effects in the intrinsic magnetic properties (Curie-temperature, saturation magnetization) and in the domain magnetism (coercitivity, h ysteresis, remanence) are treated from elementary basic principles to the description of complex systems such as interacting magnetic cluste rs. By examples taken form the recent literature the most hot topics o f the field are illustrated, and more recent or expected applications are also mentioned.
