Magnetization Analysis by Spin-Polarized Scanning Electron Microscopy

Figure 5

Magnetic-domain images of recorded bits of various lengths: (a) 254 and 127 nm, (b) 64 and 42 nm, and (both in (a) and (b)) 25 nm. A short bit length of 25 nm recorded as background can be clearly observed between the main signals. Reproduced from [7] with permission.
