【 摘 要 】

The effect of doping Ag on the oxygen content of Y0.90La0.05Eu0.05Ba2Cu3O7-d (YLEBCO) superconductor has been carried out. YLEBCO superconductor was synthesized by the addition of Ag with the variations of 0.010, 0.025, and 0.050 of molar ratio. The synthesis process was made using a wet-mixing method with calcination at 600 °C for 3 hours and sintering at 900 °C for 5 hours. The samples were characterized by means of X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), and Micro-Oxygen. The results of XRD analyses showed the domination of YLEBCO-123 phase with a volume fraction of between 85-92%, while the impurity phase Y-113 was also detected with a volume fraction between 8-15%. The increase in Ag (0.010-0.050) gave rise to enlarge the Meanwhile, the smaller change on b (3.891971-3.884080 A) was observed with the increase in Ag content. Orthorhombic strain decreased (1.593%-1.126%) with the increase in doping Ag. The addition of Ag doping caused YLEBCO oxygen content decreased (6.938-6.674 A).
