Abstract
The leakage field produced by sharp ferromagnetic probes employed for magnetic force microscopy has been investigated by electron holography . Interference fringes obtained with the double exposure technique are found to be in good qualitative agreement with calculations based on a macroscopic dipole model for the sensor tips. We show that it is pos sible to measure the probes' magnetic flux through the evaluation of t he phase difference in the simulated map.
