Abstract

The switching field and magnetization process of sub-micrometer scale magnetic elements for antiparallely coupled ferromagnetic system was studied micromagnetic simulation. The system reduced the magnetostatic field and produced a torque for magnetization reversal by an external field. The switching field of the antiparallel structure of the trilayer was found to be lower than ferromagnetic single film for above aspect ratio=2 and below width=150 nm.
