Burns, Neel, and structural phase transitions in multiferroic Pb(Fe2/3W1/3)O3 -xPbTiO3 detected by an acoustic emission
Original language description
We investigated the ceramics samples of multiferoic solid solution of relaxor ferroelectric Pb(Fe2/3W1/3)O3 with ferroelectric PbTiO3 (abbreviated PFW-xPT; x = 0, 0.25 and 0.37) by means of acoustic emission (AE) method and simultaneously using the dielectric measurement below 700 K. A distinct AE response have been detected at Burns temperature Td 640650 K, where the dynamic polar clusters start to appear, at intermediate temperature 510520 K, where the polar clusters become probably static, at ferroelectric phase transition temperatures Tc, and at Néel antiferromagnetic phase transitions. The Néel temperatures TN in ceramics were observed lower than in the crystals, the origin is discussed.
