ABSTRACT: The strong electro mechanical coupling exhibited by the ferroelectric materials is the
remarkable feature of these materials. Therefore, they find applications in sensors, actuators for
producing ultrasonics and micro positioning. The material dichloridoglycine zinc dihydrate is a
centrosymmetric ferroelectric crystal. In the present study, this crystal has been grown from a
mixture of glycine and zinc chloride. The dielectric constant and the dielectric loss of the grown
crystal were studied as a function of frequency and temperature, and the corresponding
relaxation time (τ), relaxation frequency (Fr) and the activation energy have been calculated. The ferroelectric property of the crystal has been confirmed by dielectric studies. The
ferroelectric characteristics of the crystal have been studied and reported.
