MFM is a measurement technique that uses a probe coated with a magnetic film to measure the leakage magnetic field occurring near the sample surface and obtain magnetic information.
- Qualitative information on the magnetic properties of the sample can be obtained. - Imaging of attraction and repulsion due to leakage magnetic fields is possible. - A signal of magnetic force proportional to the magnitude of the gradient of the leakage magnetic field can be obtained, but quantitative evaluation is not possible. - AFM images can also be obtained simultaneously.
