Abstract

The magnetic images of a magnetic reference sample were compared using point and thin-film magnetic force microscopy (MFM) tips. The thin film MPM tip was made by magnetron sputtering of an amorphous metal. The point MFM tip was made by an ion muling process that produces a small magnetic particle on the cantilever. Our results clearly demonstrated that the volume of magnetic material involved in the tip-sample interaction is much reduced in the case of the point tip than in that of the thin film tips. By comparing the magnetic images of a tri-bit pattern on a magnetic reference sample, we observed an improved resolution using a point MFM tip.
