“…Furthermore, the magnetic peak was much sharper than the electrostatic, so the electrostatic signal acted more as a spurious background signal. Thus the linescans shown in [13] still represent the character of the tips in that study, although the values of the field peaks may not be as accurate as first thought.…”

“…The electrostatic effects in this study are slightly larger than anticipated by the simulations shown earlier. Other tomographic studies of MFM tips performed previously have not exhibited such extreme effects [7,13]. However, careful examination of the data for the 50 nm METGLAS tip in [13] (for example) does reveal evidence of a small amount of charging, centred on the rotation axis.…”

“…However, careful examination of the data for the 50 nm METGLAS tip in ref. 13 (for example) does reveal evidence of a small amount of charging, centred on the rotation axis. Examination of the deflection data used in that study indicates that the magnitude of the Lorentz deflection signal due to electrostatic charge was slightly less than half than that of the magnetic signal.…”

Using the technique of differential phase contrast (DPC) Lorentz electron microscopy, the magnetic stray field distribution from magnetic force microscopy tips can be calculated in a plane in front of the tip using tomographic reconstruction techniques.Electrostatic charging of the tip during DPC imaging can significantly distort these field reconstructions. Using a simple point charge model, this paper illustrates the effect of electrostatic charging of the sample on the accuracy of tomographic field reconstructions. A procedure for separating electrostatic and magnetic effects is described, and is demonstrated using experimental tomographic data obtained from a modified MFM tip. J. Scott et al
