The extrinsic magnetic behaviour of ferromagnetic materials strongly depends on its magnetic structure, which is in turn strongly determined by magnetic anisotropies. Two magnitudes that play an important roll in the domain structure are i) magnetostriction, which relates the sample stress with the magnetization orientation (M) and ii) coercivity, which indicates the mobility of the domain walls. In this work, the magnetic microstructure of Finemet ribbons (Fe73.5Si13.5B9Nb3Cu1) was investigated.
