“…7 In the work by Takenaka et al, 4 the appearance of a pinched polarization-electric field hysteresis loop observed in polycrystalline BNT-5BT at elevated temperatures was taken to be the result of a FE-AFE transformation. However, considering that the pinching in polarization hysteresis can be caused by many different mechanisms such as relaxor to FE transition, 8 AFE to FE transition, 9 or severe aging in FEs, 10 the identity of the high temperature phase in the BNT− 100xBT system remains unclear.…”

Polycrystalline 0.94(Bi1/2Na1/2)TiO3–0.06BaTiO3 samples were tested under uniaxial mechanical compression at various temperatures in the vicinity of the polar tetragonal to nonpolar tetragonal phase boundary. They are shown to display double loop-like stress-strain behavior, marked by a closed ferroelastic hysteresis loop. Thus, it forms a mechanical analog to the polarization-electric field hysteresis behavior of barium titanate above the Curie temperature. As temperature is increased there is an apparent loss of macroscopically observable ferroelasticity, despite the persistence of tetragonality. Macroscopic experimental results are discussed in conjunction with temperature-dependent and stress-dependent high-energy x-ray diffraction data. This reveals a phase transition below the Curie temperature, marked by a discontinuous change in lattice parameters and octahedral tilting during compressive mechanical loading.

“…Their effect is opposite to that of donors such as: they stabilize the domain structure [10][11][12][13] and are, therefore, often referred to as "hard" dopants. They also tend to promote pronounced "aging" features, e.g., the change in permittivity with time.…”

X-ray diffraction analyses show that all the profiles are best-fitted with a cubic symmetry where Fe doping tends to induce a lattice expansion, while Nb doping does the opposite. The strain and polarization characteristics are enhanced and suppressed by the acceptor and donor dopants, respectively. The improvement in the electrical properties with acceptor doping is accompanied by the stabilization of a ferroelectric order. Electron paramagnetic resonance spectroscopic analysis suggests that the stabilization of the ferroelectric order by the Fe dopant originates from the formation of

“…Recent studies revealed that more than one process of aging may be active in one material. 8,9 Since the volume effect is related to the migration of charged carriers, both the thermodynamic and kinetic behaviors of these carriers should be considered. The crucial role played by the migration kinetics of point defects has been demonstrated in Al 3þ -doped BaTiO 3 ceramics, 10 where the Al 3þ -doping leads to lattice shrinkage and suppresses the FE aging effect at high level doping.…”
