Into a new eld of force microscopy: magnetic resonance force microscopy (mrfm) or nano-mri [1, 2] the technique is based on a force interaction measurement between an the technique is based on a force interaction measurement between an. Magnetic resonance microscopy (mrm) is an imaging method that allows the visualization of internal body structures using powerful magnets to send energy into cells, mrm picks up signals from inside a specimen and translates them into detailed computer images mrm is a useful tool for scientists. We study theoretically the magnetic resonance force microscopy (mrfm) technique of oscillating cantilever-driven adiabatic reversals, for the case when the cantilever tip oscillates parallel to the surface of a sample the main contribution to the mrfm signal is associated with a part of the resonance slice near the surface of the sample the.
