Abstract

In this work, the synthesis of solid solutions type Ba_1-xEu_xTi_{1-x / 4}O₃ (x = 0.001 and x = 0.005% by weight Eu³⁺) and its subsequent determination of electrical and magnetic properties was carried out. The samples were synthesized by the conventional solid state reaction method. The grinding of the BaCO₃, TiO₂ and Eu₂O₃ precursor powders was carried out in an agate mortar with acetone as a control medium. The powders were mixed and calcined at 900 ° C, then green pellets were manufactured which were sintered at 1350 ° C for 5 hours. The experimental results obtained by x-ray diffraction showed the presence of tetragonal BaTiO₃ phase in the BaTiO₃ sample doped with Eu₃₊ x = 0.001 and x = 0.005% by weight. Electrical measurements (Capacitance and permittivity) and magnetic measurements were made. Scanning electron microscopy results showed mostly sintered sub-rounded particles.
