Abstract

Morphotropic phase boundary (MPB) in ferroelectric materials leads to improved properties due to the structural instability. The manganese modified Pb(In_1/2Nb_1/2)O₃-Pb(Mg_1/3Nb _2/3)O₃-PbTiO₃ crystals with MPB composition were investigated, the structure/property relationship was established. The tetragonal side MPB (coexistence of 91% tetragonal and 9% monoclinic phases) was confirmed by X-ray synchrotron data, while relaxor behavior was detected by Raman characterization and dielectric measurement. Crystals with such MPB composition possess high "figure of merit" (d₃₃· Q₃₃ ∼ 10⁶ pC/N), being one order higher when compared with their pure rhombohedral counterparts. Together with high Curie temperature (∼229 °C) and temperature stability of properties, demonstrating a promising candidate for high power transducer applications.
