“…Moreover, deep E(T) minima (curves 1, 2 and 3) were found at temperature of ∼475 K < T d . The Q −1 (T) maxima corresponding to the E(T) minima can be also observed in Figure 1 It should be noted that frequency dependences of elasticity and anelasticity are characteristics of relaxors [7][8][9]. Usually, elastic and anelastic anomalies of relaxor nature are shifted to higher temperatures as measurement frequency increases.…”

Elastic and anelastic properties of the relaxor 0.55SrTiO 3 -0.45BiScO 3 ceramics were studied. Anomalous behavior of the Young's modulus and the internal friction were observed at cooling below the Burns temperature T d ≈585 K. Both elastic and anelastic anomalies were found to be frequency dependent. Elastic softening is assumed to be due to an electrostriction relationship between spontaneous polarization of polar tetragonal nanoclusters and a strain of unit cell. It was found that the internal friction anomaly observed below T d is in fact superposition of two maxima. Higher temperature maximum is typical for relaxors. Using the special internal friction mechanism for the first order phase transition, the size of the polar tetragonal nanoclusters was estimated to be equal to ∼10 nm. Such sizes of tetragonal islands were found for the sample under study by using the electron backscattered diffraction method.

“…As it known, relaxors are characterized by many anomalous physical properties in the broad temperature interval of diffused phase transition [1][2][3]. For the explanation of peculiarities of physical properties of relaxors authors use some models such as: the model of composition fluctuation [4,5], superparaelectric model [6], the model of composition ordering [7], the models of random fields [8,9], random bonds-random fields [10], etc.…”

The system of solid solutions (1-x)PbMg 1/3 Nb 2/3 O 3 -xPbZr 0.53 Ti 0.47 O 3 (PMN-PZT) was investigated. On the base of the experimental study of dielectric spectroscopy, dielectric nonlinearity under external bias field up to 15 kV/cm, and differential thermal analysis the crossover from relaxor to ordinary ferroelectric state has been revealed. Criteria allowing to draw a distinction between relaxor and ordinary ferroelectric states are discussed.

The low‐frequency elastic and anelastic properties of the ceramic 0.55SrTiO3–0.45BiScO3 sample have been studied. Anomalous changes of the Young's modulus and the internal friction characteristic for the ferroelectric relaxors were observed at cooling below the Burns temperature at ∼585 K. The relaxor properties of this system are confirmed by dielectric measurements and attributed to the coexistence of the polar tetragonal P4mm phase and the nonpolar cubic Pm3m phase. Elastic anomaly is assumed to be due to electrostriction relationship between spontaneous polarization of polar tetragonal domains and strain of the sample. Using the special internal friction mechanism for the first order phase transition, the size of the polar phase nuclei arising at the Burns temperature was estimated to be equal to ∼20 nm.
