| English abstract | This paper presents the effect of different parameters that affect the preparation of calcium and terbium manganite (TbxCa1-xMnO3) through the chemical coprecipitation method. The parameters studied were: the temperature of the heat treatment, the working pH and the dopant´s concentration values. Samples powders were characterized with X-ray diffraction (XRD). Then electron paramagnetic resonance (EPR) was performed. The results of XRD patterns revealed that the single purity phase was obtained at pH 10 with a concentration range from 0.35 to 0.45 at 1000º C. Finally, by EPR we were able to determine the change of the electronic environment of manganese due to the presence of terbium |
