文摘
- •
Magnetic phase diagram shows areas in which each configuration is more stable.
- •
Vortex core can be completely neglected for β=a/R≥0.094 or
.- •
Vortex state can be made more stable by removing the highly energetic vortex core.
- •
Phase diagram may be useful for the potential use of vortices in applications.
