magnetic force microscopy magnetic resonance force microscopy Microscopy which uses a cantilever tipped with a ferromagnetic (iron cobalt) particle to directly detect a modulated spin gradient force between sample spins and the tip to scan the surface of a magnetic specimen. As the ferromagnetic tip moves close to the sample, the nuclear spins become attracted to it and generate a small force on the cantilever. The spins are then repeatedly flipped, causing the cantilever to gently sway back and forth in a synchronous motion. That displacement is measured with an interferometer to create a series of 2D images of the sample. CHMO:0002713 2010-07-25T04:51:05Z MRFM Hils
