| Zusammenfassung | We present our results on the stray field calibration of a magnetic force microscope (MFM) based on a combination of MFM with magnetooptics using indicator films (MOIF). Magnetic force microscopy has become a powerful method for high resolution magnetic stray field imaging with a resolution down to some 10 nm. MFM can be applied under various environmental conditions, it is robust against surface contaminations and non-destructive. However, MFM, in general, is not a quantitative technique. In order to obtain quantitative magnetic stray field data, different approaches for a deconvolution of the measured MFM signal were pursued. In the framework of a point-probe approximation a localized monopole or dipole moment is ascribed to the tip. A more general calibration ansatz is used by Hug and coworkers based on a transfer function. This technique requires reference samples. The Hug group uses CAMST reference samples, an unpatterned multilayered (CoxNi1-x /Pt) sample with small domain size. Their technique implicitly uses a second transfer function that relates the stray field to the sample magnetization which is not a priori known. |
