Domain decoration in dipolar coupled ferromagnetic stacks with perpendicular anisotropy
Résumé
The dipolar stray field effects between two nonuniformly magnetized ferromagnetic Co/ Pt stacks with perpendicular anisotropy are investigated by polar magneto-optical Kerr effect microscopy. Decoration of a reversed domain in the hard stack by a domain ring in the soft stack is evidenced and interpreted by magnetostatic calculations. Mirrored 360° domain walls are strongly stabilized by these interactions.
