1. Domínios ferroelétricos em cerâmicas e materiais nanoestruturados: investigação por microscopia de piezoresposta
In this work, ferroelectric domain structure was investigated by Piezoresponse Force Microscopy (PFM). To this, an Atomic Force Microscope (AFM) has been modified to use it as PFM at room temperature and at high temperatures. Ferroelectric ceramics were used in the as bulk ceramic samples of Pb(Zr0,40Ti0,60)O3 (PZT 40/60) and (Pb0,79La0,21)TiO3 (PLT 21) prod

2. Desenvolvimento de um detector de alta eficiência para espectroscopia Mossbauer de elétrons de conversão (CEMS) a baixas temperaturas (<20 K) e testes em bicamadas Fe/ (EUxPb1-x)Te / Development of a highly efficient conversion electron Mossbauer spectroscopy (CEMS) detector for low temperature (<20 K) measurements and tests on Fe/ (EuxPb1-x)Te bylayers
The 57Fe Mössbauer spectroscopy is a nuclear, non-destructive technique used for the investigation of structural, magnetic and hyperfine properties of several materials. It is a powerful tool in characterizing materials in physics, metallurgy, geology and biology field areas, especially magnetic materials, alloys and minerals containing Fe. Lately, the Conv
