Fig. 4: Magnetic domain structure of Fe-enriched soft magnetic ribbons.
The magnetic domain structure at remanence for samples in different conditions: a as-spun ribbon, and with varying crystalline volume fraction Vf of b 5.1% (L-CL), and c 8%. The magnetic domain images are displayed in pseudo-colors, with the x, y, and z components of the magnetization vector assigned to red, green, and blue, respectively. Simulated domain patterns with d wavy and curled domains, e stripe domains perpendicular to the Ha field indicating weak stress-induced PMA with Ku ~ 5 kJ/m3, and f closure stripe domains with a higher Ku ~ 20 kJ/m3 value, with a noticeable reduction in stripe width.
