Shift of Neel temperature in (BiFeO3)1-x/(BaTiO3)x composites

The study aims at investigating dielectric properties and DTA signal of composite ceramics (BiFeO3)1-x/(BaTiO3)x (x = 0, 0.25, 0.50, 0.75) from 300 to 720 K. The obtained results indicated that the Neel temperature determined at the peaks of dielectric constant near the antiferromagnetic phase transition in (BiFeO3)1-x/(BaTiO3) shifted toward lower temperatures with increasing barium titanate content. This anomaly was also confirmed by the movement of DTA signal peaks.
