1. Estudo de Interações Hiperfinas em Óxidos RCoO3 (R= Gd e Tb) e Filmes Finos de HfO2 por Meio da Técnica de Espectrospia de Correlação Angular Gama- Gama Perturbada / Hyper¯ne Interaction Study in RCoO3 (R = Gd and Tb) and HfO2 thin ¯lm oxides by Perturbed Angular Correlation Technique
In the present work, the Perturbed Angular Gamma-Gamma Correlation technique (PAC) was used to measure the Electric Field Gradient (EFG) in two oxide systems: RCoO3 (R = Gd, Tb) perovskite oxide and HfO2 in order to study the behavior of the EFG as a function of temperature. Electric quadrupole hyper¯ne interaction measure- ments were carried out using 111I
