“…Considering the same material used for the samples with different thicknesses, it is reasonably assumed that the properties , e and an are the same for the whole samples. This can be confirmed for by studies done in [27]. Thus, we propose to explain the differences observed on the apparent magnetic permeability for the four thicknesses (see Figure 12) by the self-magnetostriction and stress induced anisotropy described by the property s (see Figure 11).…”
