Abstract

The use of magnetic force microscopy (MFM) for characterisation of permanent magnet samples offers moderate-to-high resolution data with minimal sample preparation. The technique yields contrast mapping of the magnetic stray field distribution above the sample surface. Necessary considerations include interpretation of the stray field data to yield domain structures, influence of the topography on the observed magnetic structures, and influence of the sample stray field on tip magnetization. We have used sintered NdFeB-type materials to examine these aspects of MFM.
