Electric conductivity of (Bi_{1-x}La_{x}FeO_{3})_{0.5}(PbTiO_{3})_{0.5} ceramics obtained from nanopowders synthesized by high-energy milling from respective oxides was studied in the frequency range 10 mHz ÷ 1 GHz. At room temperatures the low-frequency conductivity was found to be dominated by the contribution from poor-conducting grain boundaries, whereas the contribution in the range 1 kHz ÷ 1...
