Phase transition and dielectric properties of La-doped Pb(Zr,Sn,Ti)O3 antiferroelectric ceramics under hydrostatic pressure

Phase transition and dielectric properties of La-doped Pb(Zr,Sn,Ti)O3 antiferroelectric ceramics under hydrostatic pressure have been studied, and effects of temperature on the pressure-induced phase transition and the dielectric property dependence on the applied hydrostatic pressure have been investigated. The ferroelectric–antiferroelectric phase transition pressure is decreased with increasing temperature, these phenomena are helpful for understanding of the behaviors of pressure-induced dielectric frequency dispersion and diffuse phase transition.
