FIG. 1.

Shift of DSC peaks of ferroelectric-paraelectric transition of a single crystal sample with increase of aging time in ferroelectric state. Aging temperature is . Arrows denote the reverse transition finishing temperature, , as defined by the inset. “Deaged” means that the aged sample is heated to paraelectric phase and held for a certain period to remove the aging effect before cooling again into ferroelectric phase.

Reverse transition temperature of a single crystal sample as a function of ferroelectric aging time at different temperatures.

FIG. 3.

Shift of DSC peaks of ferroelectric-paraelectric transition of ceramics with increase of aging time in ferroelectric state. Aging temperature is . (See Fig. 1 for explanation of deaged and arrows.)

Symmetry-conforming property of the short-range order (SRO) of point defects in perovskite crystals. Black areas in ◑ represent the conditional probability of finding a point defect around a given impurity in site 0. The crystal symmetry and SRO symmetry can be expressed in a simple symbolic representation as shown below. Square and rectangle represent higher and lower symmetry, respectively. (a) Cubic phase: , , (b) tetragonal polar phase: , . Arrows in rectangle represent the symmetry with polar axis.
