• Micromagnetic simulation
• Cross-tie domain walls
• C-shaped domain walls
• Permalloy films

Magnetization distributions and energy of 180-degrees domain walls in a stripe film were investigated over a wide film thickness range. Three-dimensional numerical simulations are performed. Two kinds of transitions between stable domain wall configurations were obtained: from Neel walls to cross-tie walls and from cross-tie walls to asymmetric Bloch (C-shaped) walls. The latter kind of transition was investigated for the first time. The transition from the two-dimensional cross-tie structure to the three-dimensional one during the rise of the film thickness was demonstrated.
