The work presented in this thesis is a study of the magnetic properties of various magnetic force microscopy (MFM) tips using Lorentz electron microscopy and tomography. The implementation of tomography and differential phase contrast (DPC) microscopy allows the stray field distribution in the half space in front of MFM tips to be measured with a spatial resolution of <30 nm and a field resolution of <2 mT. This information will allow the development of better models for MFM imaging performance and, potentially, the quantification of MFM images.
