Abstract
Investigation of the substitution process can provide a better understanding of the superconducting mechanisms in cuprous oxide materials. In this work the effects of substitution Lanthanum (La) for Gadolinium (Gd) on the structure and oxygen content for x = 0.0 - 0.5 in the compound Gd 1-x La x Ba 2 Cu 3 O 7-δ (GLBCO-123 phase) have been investigated. Samples were synthesized by using a wet-mixing method from powders of Gd 2 O 2 , La 2 O 2 , BaO, CuO, and solution of HNO 3 . Based on the analysis of XRD data and SEM-EDXA, it confirms that the sample has formed the GLBCO-123 phase, as expected. It has been obtained that the lattice parameters a and c are increased while the parameter b is slightly decreased with increasing content of Lanthanum. The oxygen content slightly decreased and structure of the Gd 1-x La x Ba 2 Cu 3 O 7-δ phase changed from orthorhombic to tetragonal with increasing the content of Lanthanum.
