The study of magnetic materials engineered on the nanometre length scale is one of the most active areas of condensed matter physics today. A means of visualising magnetisation distributions with nanometre scale resolution is essential both for fundamental investigations and for improving hard disk media, read-write heads and magnetic memory chips. A number of experimental techniques exist to do this, but each has its own drawbacks. One of the less well studied techniques is Scanned Hall Probe Microscopy (SHPM), in which a Hall probe is scanned over a surface using an Atomic Force Microscope. The relatively large size of the Hall probe usually limits the resolution of SHPM close to the micrometre scale. We propose to use Focused Ion Beam Milling to attempt to fabricate nanometre scale Hall probes and to integrate one onto the apex of an Atomic Force Microscope tip. If successful, this will provide a scanned probe magnetic microscopy which is highly sensitive, has high spatial resolution, does not require special sample preparation and which does not perturb the sample under test.
