Description:
The Atomic Force Microscopy (AFM) is a method which allows scientists to examine the surface properties of samples with high spatial resolution. This method is based on the measurement of force interaction acting between the probe and surface of the sample. The probe is a sharp tip located at the free end of a flexible cantilever. It is subsequently brought into tight vicinity of the sample surface. Mechanical changes of the cantilever induced by acting of atomic forces are detected by optical system.
The Magnetic Force Microscopy (MFM) is an operational mode of Atomic Force Microscope which enables to measure the magnetic field gradients over the surface of the sample.
