Scheme of the envelope for a cantilever beam vibrating at the second order flexural vibration mode (upper part). A magnetic monopole point probe (circle) and a spacer element are indicated. The same cantilever vibrating at the conventional first flexural mode (lower image). The coordinate system in use is indicated.
SEM micrographs of a MFM probe based on a FeCNT. The probe provides both in-plane and perpendicular magnetic sensitivity. (a) The low magnification image shows one half of the Si cantilever including the free end. (b) Spacer element with FeCNT. The FeCNT was attached by electron-beam induced local deposition of carbon. (c) High magnification image of the FeCNT's free end. The enclosed iron nanowire is clearly visible.
(a) and (b) MFM phase shift images at the same location of a magnetic hard disk. The free end of the probe's Fe nanowire shown in Fig. 2 was vibrating (a) in the z-direction and (b) in the x-direction. The excitation frequencies are 89.29 kHz (a) and 559.8 kHz (b). The full color range corresponds to 1000 mdeg (a) and 80 mdeg (b).
MFM field derivative data along section A of Fig. 3.
