Abstract

Quantitative analysis of magnetic force microscope (MFM) images is only possible if the magnetic state of the sensing tip is known. In this paper we describe a method which is used to characterise the stray field produced by an MFM tip. The method utilises Lorentz microscopy techniques and tomographic field reconstruction algorithms. A specially constructed calibration specimen enables measurement of the absolute values of the tip stray field to be made.
