Abstract

In this paper we consider the problem of optimization of shapes and sizes of MFM probes to realize the maxi­mum MFM contrast from small ferromagnetic particles was shown that for all probes there are optimal shape parameters connected with probe-particle dipolar interaction. The optimum is defined both by the geometry of the probe and by the structure of the magnetic field of investigated objects. The calculations which were per­formed for the spherical nanoparticle show that in general the tip size should be approximately equal to the size of investigated particle. Keywords: magnetic-force microscopy, MFM tips, MFM phase contrast, ferromagnetic nanoparticles.
