ABSTRACT
The diffusive motion of the conducting electrons in the one-dimensional organic conductor FA2PF6 (FA, Fluoranthene) is studied with the ESR pulse-gradient spin-echo (PGSE) signal combined with spatial density ESR imaging. A local measurement of the short restricted regions reveals diffraction patterns in the local PGSE data. A model calculation adapted to the local measurements provides a highly accurate quantitative description of the results. The appearance of these patterns provides information about the diffusive motion of the charge at the crystal boundaries.
