Abstract

The study of domain images in advanced magnetic materials is central to their further development and exploitation. For nanophase exchange-coupled magnetic materials, high spatial resolution is required for both topographic and magnetic imaging. In this paper we make a direct comparison of magnetic force microscopy and Lorentz microscopy, in order to establish the degree of complementarity and agreement between the two techniques. Examples will be drawn from both hard (Nd-Fe-B) and soft (Fe-based) nanophase magnetic materials
