Second order tetragonal-to-cubic phase transition in Sr0.5Ba0.5HfO3

Autor: R. E. Alonso, A. R. López García, Alberto Caneiro, D. G. Lamas, C. M. Horowitz

Publikováno v: Solid State Communications. 120:205-210

We report the crystal structure together with the electric field gradient (EFG) tensor at the Hf site in Sr 0.5 Ba 0.5 HfO 3 as a function of temperature. High-temperature X-ray diffraction data show a second-order tetragonal-to-cubic phase transitio

Study Of Phase Transition In Nanostructured ZrO[sub 2]-CeO[sub 2] Solid Solutions By Synchrotron Radiation

Autor: L. M. Acuña, D. G. Lamas, R. O. Fuentes, M. C. A. Fantini, Rogério Magalhaes Paniago

Publikováno v: AIP Conference Proceedings.

In this work we studied the tetragonal to cubic (t‐c) phase transition as function of temperature in compositionally homogeneous ZrO2‐CeO2 powders by synchrotron radiation X‐ray diffraction (SR‐XRD). Transitions are correlated with changes in
