The irreversibility of the antiferroelectric (AFE) to FE phase transition in Pb1-x Bax Zr O3, x=0.75-0.1, compositions is shown to be a consequence of lattice vacancies arising from PbO evaporation during ceramic processing. Previously, the absence of a FE→AFE cooling transition was thought to be du...
