In this paper dielectric spectra of 0.6PMN-0.4PZN ceramic obtainedfi-om broadband dielectric spectroscopy is presented. Measurements revealed an unusual relaxor like nature. Two different processes in the dielectric spectra have been observed. High frequency, or short relaxation times, behaviour is typical for ferroelectric crystals. Longest relaxation times do notfollow Vogel-Fulcher dependence, which is unusualfbi- relaxors.
