Table 1. List of the studied magnetic multilayers investigated.
The saturation magnetization Ms, the uniaxial anisotropy Hk, the measured domain periodicity, the estimated DW width, and the comparison of estimations of D with a fixed DW energy [Keff model (39)], (Δ, λ, ψ) model, and the present full micromagnetic model are given for each multilayer. Two multilayers are not labeled as they have not been studied by CD-XRMS but only characterized by MFM to determine D with the different models.
