Abstract
Micromagnetic finite element calculations describe the interactive mag netisation processes which determine the magnetic properties of rare-e arth-based composite magnets and Co/Pt multilayer structures. Sm2F17Nx -based composite magnets show better temperature stability than Nd2Fe1 4B-based magnets. In Co/Pt multilayers spatial fluctuations of the mag netocrystalline anisotropy energy create barriers for domain wall moti on. The pinning field of domains increases with increasing grain size.
