Dielectric spectroscopy of Pb1–x Ba x (Mg1/3Nb2/3) m (Zn1/3Nb2/3) y (Ni1/3Nb2/3) n Ti z O3 solid solutions in a wide temperature interval

Structure‐property relationships in BiScO3–PbTiO3–PbMg1/3Nb2/3O3 ceramics near the morphotropic phase boundary

“…It is known that near singular elements of phase diagrams (in particular the tricritical points) the functions of response, for example ε/ε 0 , have extremums . The enhancement of the dielectric response was observed close to the assumed tricritical points in the (1− x )Ba(Zr 0.2 Ti 0.8 )O 3 ‐ x (Ba 0.7 Ca 0.3 )TiO 3 , Ba(Ti,Sn)O 3 solid solutions and in the ceramics of the multicomponent system on the basis of PMN–PT . The existence of a crossover from the second to the first‐order phase transition for x > 0.42 evidenced by the characteristic behavior of the dependencies d (ε/ε 0 )/d T (Figure ).…”

“…[42][43][44] The enhancement of the dielectric response was observed close to the assumed tricritical points in the (1Àx)Ba(Zr 0.2 Ti 0.8 )O 3 -x(Ba 0.7 Ca 0.3 )TiO 3 , 45 Ba (Ti,Sn)O 3 solid solutions 46 and in the ceramics of the multicomponent system on the basis of PMN-PT. 47 The existence of a crossover from the second to the first-order phase transition for x > 0.42 evidenced by the characteristic behavior of the dependencies d(e/e 0 )/dT ( Figure 6). The same relationship was found in the xNa 0.5 Bi 0.5 TiO 3 (NBT)-(1Àx)BaTiO 3 system with increasing of BaTiO 3 content.…”

Low- and high-field electromechanical responses of relaxor-based multicomponent ceramics for application in multiregime actuators

“…33,34 Second, it exhibits pronounced relaxor ferroelectric properties. 37,38 Third, it is distinguished by ultrahigh values of electric field-induced strain (S/E $ 2000 pm/V at E $ 5 kV/cm), which makes it promising for practical applications in actuators. 34 Fourth, this solid solution has low threshold electric fields, which allows for research in a low-field mode.…”
