  Rezumat:  Permanent magnets find application in a wide variety of devices, from everyday appliances like loudspeakers to motors, data storage and medical (e.g. magnetic resonance imaging) devices. There is a constant search for new materials with superior properties, either in the form of new magnetic compounds or in the form of known materials with improved magnetic properties. Modern high-performance magnets are based on intermetallic compounds of rare-earths (R = Nd, Pr, Sm) and 3d transition metals (T = Fe, Co) with very high magnetocrystalline anisotropy, such as Nd2Fe14B and SmCo5 [1-3]. FePt magnets with the L10 structure have recently attracted much attention because of their potential usage in ultra high-density data storage and permanent magnets for special applications. The material design on a nanoscale is one of the possibilities to improve the magnet performance. In this presentation, the complex relation between the structure, microstructure and magnetic properties of modern high-performance magnets will be reviewed.
