Resumen

A structural study of the incorporation of Pr-ion into the Y-site was realized in polycrystalline samples of (Y1-xPrx)Ba2Cu3O7 through of Rietveld analysis of X-ray diffraction patterns, bond valence method and electronic density diagrams. The crystalline structure stabilized into orthorhombic phase (Pmmm) for x=0, but the unit cell increases its symmetry by doping the Y-site and stabilizing into a tetragonal phase (P4/mmm) for x=0.5. Moreover, the structural results obtained were correlated with the magnetization measurements, where the Tc decreased from 90K (x=0.0) to 49K (x=0.3). The oxygen content in the compounds was checked by means of μ-Raman spectroscopy, observing the frequency position of O(4)-Ag phonon mode.
