Abstract :
Micromagnetic modeling was performed to verify that antivortex states interacting with vortex states can play a crucial role in M dynamics in confined and semi-continuous model systems. Results offer comprehensive insights into the understanding of the static or dynamic properties of M reversal processes, and new features or more details of domain and domain-wall structures observed in continuous real films.
