Abstract (EN): Nanometric magnetic systems are of growing importance, displaying novel magnetic properties which are of both fundamental scientific interest as well as of practical importance. There are several types of system which can be classified as nanometric, which depend on the fabrication process, for example, amorphous / nanocrystalline alloys, immiscible alloys (e.g. Co-Cu), nanostructured films and discontinuous multilayer systems. In whatever case, magnetic confinement effects and the interactions between magnetic particles, via an intervening phase, give rise to the particular magnetic behaviour and properties of the system in question. Ferromagnetic resonance (FMR) is a powerful technique for the study of magnetic properties and has been applied to many different types of magnetic system. FMR essentially measures the internal effective field to which a spin system is subject and as such can reveal useful information on fundamental magnetic properties such as the g-factor, magnetisation, magnetocrystalline anisotropies and shape effects. In the present paper we present experimental results of FMR studies of FeZrCuB amorphous/nanocrystalline alloy, FeAl cluster systems and the discontinuous multilayer system Al2O3[CoFe(t)/Al2O3](10), where t is the effective thickness, ranging from 7 to 13 Angstrom.
