MFM (Magnetic Force Microscopy)

Magnetic Force Microscopy (MFM) is a technique used to visualize magnetic properties at a very small scale, often at the level of individual nanostructures. It works by scanning a sharp, magnetized tip very close to a sample's surface. The magnetic forces between the tip and the sample affect the tip's motion, which a sensor detects. This information is then used to create detailed images showing how magnetic fields are distributed across the sample. MFM is valuable for studying magnetic materials and devices, helping scientists understand and optimize their magnetic behaviors at the microscopic level.
