Structural and magnetic analysis of the Pr1.5Eu1.5Ba5Cu8O18 system

This research describes the synthesis and characterization of the Pr1.5Eu1.5Ba5Cu8O18 system, obtained by the solid-state reaction method. For the synthesis of this material, oxides of Pr6O11, Eu2O3, BaO and CuO were used. The sintering temperature was 900°C. The structural analysis of the synthesized systems was carried out using X-Ray Diffraction (XRD), with a comparison with theoretical patterns and validated with Rietveld refinement analysis, obtaining a type P2mm crystallographic orthorhombic system with a=3.892454Å, b=3.894411Å and c=31.155851Å. The characterization by means of Scanning Electron Microscopy (SEM) let us conclude that the material presents homogeneous granular morphology. Finally, the magnetic response of this material is determined by the magnetization curves as a function of the applied magnetic field 50K and as a function of temperature 2000Oe.
