Relaxor freezing and electric-field–induced ferroelectric transition in a lanthanum lead zirconate titanate ceramics

Transition lines between various phases in the electric-field–temperature phase diagram of 9/65/35 lanthanum lead zirconate titanate ceramics were determined by measurements of the temperature and electric-field–dependent dielectric constant. Above the critical field (EC) the dc bias electric field induces a transition from the relaxor to the ferroelectric phase, while below EC the system exhibits a freezing transition between the ergodic and nonergodic relaxor state. Transition lines are discussed in terms of the spherical random-bond–random-field model of relaxor ferroelectrics. Measurements in the quasistatic temperature regime confirm the prediction of the model that the nonlinear dielectric response shows a sharp peak at the freezing transition temperature.
