Magnetic properties of quasi-three-dimensional Fe thin film studied by spin-polarized secondary electron microscopy

The magnetic domain structures of Fe thin films on two dimensionally arranged hexagonal land-and-groove structures have been studied by spin-polarized secondary electron microscopy. Characteristic magnetization reversal was observed for the hexagonal land-and-groove structure in a remanent state. The coercivity difference between the land and groove was partly due to the difference in surface roughness between the land and groove. Shape-induced anisotropy also contributed to the magnetization reversal process.
