摘要
Positive muons can be implanted into organic and molecular magnets in order to study their internal magnetic field distribution and any associated dynamics. The muon behaves essentially as a "microscopic magnetometer", sensitive to local magnetic order and magnetic fluctuations. We describe some recent experiments using this technique which were performed on a variety of organic systems, including nitronyl nitroxide magnets and materials with spin-Peierls ground states, MF-M(TCNQ)(2) and DEM(TCNQ)(2), and demonstrate how the technique can give information concerning their ground states.
