FIG. 3.

MFM images showing maze-like magnetic domain structures with periodicity 3 to 5 μm (scan area: 20 μm × 20 μm) taken with bimorph driven system (a) and electrostatic force modulation system (b).

FIG. 4.

(a) Transition from magnetic domain imaging mode to topographic imaging mode during tip-scanning of CoCr film with set-amplitude 85 nm using bimorph driven modulation (scan area: 40 μm × 40 μm). The bimorph driven system is more susceptible to large topographic features such as the feature indicated by an arrow, which causes the imaging mode to change from magnetic to topographic. (b) Magnetic domain image of CoCr film in the noncontact regime with set-amplitude 95 nm operating at the resonance frequency 53 kHz using the electrostatic force modulation system (scan area: 40 μm × 40 μm). The system is robust against frequent tip-collisions with topographic hillocks such as the feature indicated by an arrow.

FIG. 5.

(a) Amplitude vs. distance data for the bimorph system. Note the identical feedback polarity in the noncontact and tapping regions. The dashed line fits the data with 1/z. (b) Amplitude vs. distance data for the electrostatic force modulation system. Note the barrier between the noncontact and tapping regions and the opposite feedback polarity (sign of slope) in each region. The dashed line fits the data to the logarithmic function b×log(D/z).

Image of FIG. 6.
FIG. 6.

A comparison between the bimorph driven system (a) and electrostatic force modulation system (b) during the magnetic force imaging acquisition. The shaded profiles represent the topographic features, whereas the solid lines represent the sectional profiles in the magnetic force images. The oscillatory lines depict the motion of the cantilever with magnetic probes.
