FIG. 1.

(a) Schematic to illustrate the magnetization configuration in a multidomain MFM probe. For simplicity of illustration, an antiferromagnetic probe is shown. The red region shows the tip region where the magnetization in the two layers does not cancel out. This “unbalanced” region defines the resolution of the probe. (b) MFM images of regions in reference magnetic disks with continuously recorded sub-100-nm wide tracks of varying linear densities read back by a state-of-the-art commercial probe (left image) and a sub-10-nm-resolution multidomain MFM probe.

FIG. 2.

A power spectral density analysis of a MFM image with high-density patterns.

Image of FIG. 3.
FIG. 3.

(a) Schematic illustrating a saturated (single domain) state of the bilayer MFM probe. (b) MFM images of regions in reference magnetic disks with continuously recorded sub-100-nm wide tracks of varying linear densities read back by a sub-10-nm-resolution multidomain MFM probe (left image) and the same probe in a saturated state, respectively.
