    • Note that a transfer function theory is also possible in the case of a MFM tip above a superconductor in the Meissner state (soft sample) (Ref. 16).

    • note
    • Here we treat only perpendicularly magnetized samples. However, the application of transfer functions to an arbitrarily complex micromagnetic structure including in-plane magnetization components is straight forward.

    • note
    • 4 cantilevers. Due to their low mass, the energy stored in the cantilever oscillation is small and the damping caused by air flowing in and out the gap formed by the relatively flat pyramid tip and the surface of the sample becomes severe.

    • note
    • The temperature plays an important role. Measurements performed at 3 K instead of room temperature will improve the minimal detectable force derivative by a factor of ten. Further the decreased drift rate at low temperatures allows long measurement times and therefore reduced measurements bandwidths, Δν leading to improved force sensitivity.

    • note
    • A similar procedure would be applicable to scanning tunneling microscopy data (exponential decay of the corrugation above a periodic atomic structure) as well as to scanning near field optical microscopy data (exponential decay of the evanescent light field of a standing surface wave).

    • note
    • Note that many of the small domains would be missed by the discrimination plane if the original data is used instead of the working image with its reduced tip-to-sample distance. However the exact amount of the reduction and the assumed tip-to-sample distance of the measured data are not sensitive parameters. Here we assume the tip-to-sample distance of the measured data to be 170 nm and the reduced tip-to-sample distance to be 150 nm.

    • note
    • The magnetic charge-to-sample distance of 176 nm is larger than the distance between the physical end of the tip and the sample (≈100 nm) as determined from the experiment. This is reasonable given the radius of curvature of the tip (50-100 nm).
