Abstract
Novel implementation of the Fourier imaging technique on conduction electron spins in the one-dimensional organic conductors (FA: fluoranthene) is reported. Two-dimensional spatial imaging of resolution is combined with the pulsed-gradient spin-echo technique, to derive maps revealing the local properties of the electron spin density and mobility. The maps generally show pronounced inhomogeneity of both density and mobility on the scale of . Highly mobile regions were identified to exist, and the mobility in these was quantitatively evaluated by a basic theoretical model of restricted diffusion.
