Broad-band dielectric response of doped incipient ferroelectrics

Broad-band dielectric responses (10 2–10 14 Hz) of Sr 1-1.5 x Bi x TiO 3 ( x=0.0067÷0.133) ceramics and K 1- x Li x TaO 3 ( x=0.050÷14) single crystals are analysed and compared. The common features are emphasized: softening of the polar phonon is suppressed by the doping, dielectric dispersion take...
