Abstract
It is known that the cation substitution in perovskites produce changes in the macroscopic properties of these materials. A case to study is for example the influence of cation B partially substituted by cation B{sup `} when ABO{sub 3} is ferroelectric, and A B{sup `}O{sub 3} is paraelectric. In this work the system Ba Ti{sub 1-x} Hf{sub x} O{sub 3} with x = 0.05, 0.10, 0.15 and 0.20 is studied by Perturbed Angular Correlations (Pac) in order to obtain microscopic information through the electric field gradient tensor (EFG) produced by electrons close to probes. Two hyperfine quadrupole interactions were detected. One interaction associated to probes with defects originated during the nuclear processes after neutron irradiation, and the other are located in B sites. At R T, the hyperfine parameters are analyzed in terms of Hf concentration. (author). 5 refs., 2 figs., 2 tabs.
