Co, Ni and Permalloy probes for Magnetic Force Microscopy have been characterized. The latter type of probe shows a particular behaviour which has been interpreted on the basis of the low coercivity of the Permalloy. The trend of the force due to the z-component of the stray magnetic field of digital recording media (Floptical) has been worked out, from the cantilever deflections, as a function of probe-sample distance and interpreted.
