Abstract

Calculations of the magnetic force microscopy (MFM) contrast from low-coercive ferromagnetic and superparamagnetic particles are presented. It is shown that the external field stabilizes the magnetic moment of particles, allowing the separation of contributions of van der Waals and magnetic interactions to the MFM phase contrast. The values of stabilizing magnetic fields are estimated.
