抄録

The relation between images obtained by magnetic force microscope (MFM) and the magnetization distribution of a ferromagnetic tip was investigated. Stray field from a ferrite magnetic recording head was measured by MFM, using a Co-coated ferromagnetic tip. Two-dimensional finite element analysis was carried out to compute the force derivative, where both the tip-sample magnetic interaction and the nonlinear magnetic properties of the ferromagnetic tip and the recording head were taken into account. Comparison of the MFM image and the calculated force derivative showed close agreement. The calculated magnetization distribution of the ferromagnetic tip and the MFM image was also discussed. We found that it is important to consider the magnetization distribution of the ferromagnetic tip for the interpretation of MFM images.
