With a rhombohedra-like structure, the Bi0.875Sm0.125FeO3 ceramics show much-improved ferroelectric and piezoelectric properties: a saturated ferroelectric polarization of 40 μC/cm2 and a piezoelectric d33 of 45 pC/N at 20 °C. After the polarized sample was annealed at 600 °C, its d33 decreases to ∼...
