Micromagnetic simulation of thickness variation of Neel cap in hybrid Bloch-Neel domain wall
Artikel i vetenskaplig tidskrift, 2005
The hybrid Bloch-Neel domain wall in iron film has been investigated using three-dimensional micromagnetic calculations. Magnetization distributions in the
film plane and cross-section are presented. In the film plane the rotation of magnetization in the 180 degrees domain wall takes two different patterns from the
bottom layer to the top layer. In cross-section the C-shaped magnetization distribution with hybrid Bloch-Neel domain wall has been found. The thickness of the
top Neel cap changes from its largest value as the C-shaped magnetization distribution appears, and becomes thinner as the C-shaped magnetization distribution
gradually moves and grows up. The thickness variation of the bottom Neel cap changes in a similar way, but with a reversal pattern. The results in this paper will enrich
our knowledge of magnetic domain and domain wall patterns in magnetic materials.
