Scheme of the HIDW model. The z axis coincides with the uniaxial easy axis for both antiferromagnetic and ferromagnetic layers. The external reversing magnetic field is applied in the − z direction. The magnetic moment directions on both sides of the antiferromagnetic layer are allowed to rotate away from the easy axis by angles α 0 and α . The magnetization in the FMDW rotates from an angle β at the interface to γ , forming the domain wall thickness δ FM. Beyond the FMDW, the magnetization is assumed to rotate uniformly by γ in the ferromagnetic domain. The difference between spin directions across the interface, α – β , corresponds to an inter-space ξ .
