| Abstract: | Magnetization process and switching field of sub-micron sized elements for antiparallely coupled ferromagnetic systems (ferromagnet/nonmagnet/ferromagnet) are studied with micromagnetic simulation using Landau–Lifshiz–Gilbert equations. It is found that the switching field of the antiparallel structure of the trilayer is lower than that of the ferromagnetic single film for above aspect RATIO=2 and below WIDTH=150 nm. |
