Phys. 108, 014103 (2010) The mechanical stress-induced domain switching and energy dissipation in morphotropic phase boundary (1Àx)(Bi 1 À y La y )FeO 3 -xPbTiO 3 during uniaxial compressive loading have been investigated at three different temperatures. The strain obtained was found to decrease with increasing lanthanum content, although a sharp increase in strain was observed for compositions doped with 7.5 and 10 at. % La. Increased domain switching was found in compositions with decreased tetragonality. This is discussed in terms of the competing influences of the amount of domain switching and the spontaneous strain on the macroscopic behavior under external fields. Comparison of the mechanically and electrically dissipated energy showed significant differences, discussed in terms of the different microscopic interactions of electric field and stress.

“…A very sharp hysteretic quasistatic strain curve and polarization jumps accompanied by a dramatic change in stiffness (by a factor of 6-8) at stress less than 15 MPa have been reported first in the PZN-PT crystals [7]. However in PMN-PT crystals, the effect was more diffuse and continuous [13]. Later this elastic nonlinearity was also reported in different crystals and was shown to be a strong function of temperature and geometry of the crystals [16][17][18].…”

“…Therefore, by making the field induced phase transition to occur at significantly lower electric fields and at much faster rates would make it possible to create a material with high effective piezoelectric properties. Recently, it was shown that domain-engineered relaxor-FE crystals with 4 mm and 2 mm macrosymmetries exhibited a large and reversible phase transformation strain under mechanical compression that is tunable by an electric field [7][8][9]13].

Fundamental shortcomings of ferroelectrics (FEs) are low induced strain and high electric field often required for practical application in actuation, sensors, and acoustics. Although domain engineered FE single crystals deliver an order of magnitude improvement, fatigue remains another drawback in achieving reliable multiple domain switching crucial for memory storage. We demonstrate that under specially compressive stresses FE relaxors exhibit low field induced reversible and sustainable strain associated with FE-FE phase switching and unusual and unexpected lack of fatigue after several millions cycles is believed due to strain accommodation occurring in ferroics. Polarized light microscopy and X-ray diffraction are in a very good agreement with macroscopic observation and phenomenological model confirming proposed transformational path. The phenomena presented in this work are envisioned to be universal in domain engineered ferroics enabling mechanical stress to be used for strain and polarization control of electromechanical energy conversion.

“…The electrostrains can be enhanced to be over 1% in these crystals via electric field induced ferroelectric phase transitions. However, the high cost of single crystals and the quick drop of electrostrain upon applying a moderate prestress [6][7][8] make these materials not suitable for industrial actuations. ii) Developing lead-free piezoelectric ceramics [9][10][11][12].…”

“…The currently used lead titanate zirconate (PZT) based stack actuator is always suffering from its small output strain(typically ~0.1-0.15%), which is much smaller than that by the shape memory alloys (~several percent) [2] and also smaller than that by the giant magnetostrictive materials, Terfenol-D (~0.2%) [3]. In the past decades, various approaches have been adopted to enhance the electrostrains in ferroelectrics which can mainly be classified into three types: i) Developing relaxor ferroelectric single crystals [4][5][6][7][8]. The electrostrains can be enhanced to be over 1% in these crystals via electric field induced ferroelectric phase transitions.…”

The widely used ferroelectric ceramics based actuators always suffer from small output strains (typically ~0.1-0.15%). Non-180° domain switching can generate large strain in ferroelectrics but it is usually irreversible. In this work, we tailored the domain structures in a soft lead titanate zirconate (PZT) ceramic by periodically orthogonal poling. The non-180° switching in this domain-engineered PZT ceramics turns to be reversible, resulting in giant electrostrains up to 0.57% under a field of 2kV/mm (dynamic d33 * (=S/E) of 2850pm/V). The large electrostrain keeps quite stable and even slightly increases after 10 4 cycles of loading, which is very promising for next-generation large-strain actuators.
