Abstract: The evolution of the characteristic frequency versus the maximum temperature is discussed in terms of the Vogel-Fulcher equation. Likewise, the characteristic diffuseness of the dielectric peak is described based on an empirical Lorenz-type relation. The deviation from the Curie-Weiss law (γ = 1.623) indicates that the lead-free Ba _0.8 Sr _0.2 Ti _0.75 Zr _0.25 O ₃ ferroelectric compound reveals a relaxor behavior.
