Magnetic Domain Patterns in Bilayered Ribbons Studied by Magnetic Force Microscopy and Magneto-Optical Kerr Microscopy

Figure 4

Magneto-optical hysteresis loops (a) and domain patterns (b) of the coiled BL-FC ribbon (toroid, 13 mm in diameter). Left and right subplot correspond to the coiling with the air and wheel side out, respectively. The loops and domains are measured from the outer sides.
