(a) Influence of the GB thickness on : for the three different 2-G model structures of Figure 14 (solid lines). In comparison the GB with averaged homogeneous magnetic properties of  T   T are shown (dotted line). (b) Influence of the averaged homogeneous saturation polarization of the GB-phase on in the 2-G model structure for different GB thickness, . The 2-G model structure with a GB thickness of 20 nm has a size of  nm.
