Resumen:
Impedance sepctroscopy study of SrZrO3R.E. Alonso1, J. de Frutos2, M.A. Rubia2, M.A. Taylor1, A. R. Lopez García11IFLP, UNLP2Universidad Politecnica de MadridRecent studies on the phase transitions of SrZrO3 using X-Ray and Neutron diffraction, toghether with Perturbed Angular Correlation spectroscopies reveal that the phase diagram of this compound is not simple. The temperatures of the transitions appear to be highly dependent of the thermal history. In this work we present for the first time a study of the phase stability as a function of the annealing using the Impedance Spectroscopy technique. This work will focus on the Pnma to the Imma (second order) and the Imma to I4mcm (first order) phase transitions previously reported at 750C and 840C respectively
