What is mfm mean?

MFM stands for "Magnetic Force Microscopy," which is a specialized imaging technique used in nanotechnology and materials science. It involves scanning a small magnetic probe over a sample surface to detect variations in magnetic force. This allows researchers to visualize magnetic domains, domain walls, and defects with high spatial resolution, providing insight into the magnetic properties of materials at the nanoscale. MFM is commonly used in fields such as data storage, magnetic materials research, and semiconductor device characterization.
