Decays of diffraction efficiency of gratings written in Fe: LiNbO3 have been studied in connection with photorefractive fixing. Measurements have been carried out at different temperatures within the range of interest in photorefractive fixing, 144-168 o C. The decay curves are non-exponential and c
