The electric field gradients in perovskite SrHfO3 and BaHfO3 powder
samples were investigated by means of Perturbed Angular Correlation
spectroscopy, using implanted In-111 hyperfine probes. The measurements
cover the temperature ranges from 22 to 893 K for SrHfO3 and from 293 to
875 K for BaHfO3, respectively. In both compounds, three quadrupole
interactions were established. The largest fraction showing a pronounced
dynamic interaction is assigned to In-111/Cd-111 probe atoms on
substitutional Hf sites in both compounds. For SrHfO3, the temperature
dependence of the dynamic interaction was associated to the Pnma <->
Imma phase transition for SrHfO3 at about 700 K. We discuss the results
in relation to those obtained for In-111/Cd-111-probes in PbZrO3 and BaTiO3, and for Hf-181/Ta-181-probes in AHfO(3) (A = Ca, Sr, Ba). (C)
