N2 - © 2015 Elsevier Ltd. All rights reserved.Dielectric studies were carried out for composite ceramics (BaTiO3)x/(BiFeO3)1-x (0 <x <1) within a temperature range 23-450°C. Linear permittivity studies at various frequencies showed the emergence of peaks near the temperatures of the ferroelectric phase transition in the BaTiO3 grains and of the antiferromagnetic phase transition in the BiFeO3 grains. The positions of the peaks did not depend visibly on frequency. The permittivity peaks near the antiferromagnetic phase transition shifted to low temperature with increasing the barium titanate fraction which suggests the reduction of the Neel temperature. The decrease in the Neel temperature in the composite ceramics was confirmed by measurements of the temperature dependence of the third harmonic generation.
