摘要:
A magnetic resonance force microscope was used to demonstrate three‐dimensional nuclear magnetic resonance imaging with micrometer‐scale spatial resolution. The sample was mounted on a silicon nitride cantilever that served as a micromechanical force sensor. A nearby magnetic tip generated a field gradient of 22 G/&mgr;m. A three‐dimensional magnetic resonance force map of the1Hspins in the sample was produced by lateral scanning of the magnetic tip relative to the sample and by varying the rf frequency of the spin excitation. The real‐space spin density of the sample was reconstructed from the force map by means of a deconvolution technique. The spatial resolution achieved in the experiment was ∼3 &mgr;m in the axial direction. ©1996 American Institute of Physics.
