Magnetic Force Microscopy (MFM) is a scanning probe microscopy technique that utilizes a magnetically coated tip attached to a cantilever to measure magnetic forces exerted on the tip by a sample. By raster scanning the tip over the sample’s surface, MFM creates a map of the magnetic field distribution, allowing for visualization and characterization of magnetic domains and structures at the nanoscale.
