Ag substitution effect on NdBa2Cu3Oz high- Tc superconductor system

Abstract

Many research teams are actively studying NdBa₂Cu₃O_x-based High-T_c superconducting systems, conducting experimental and theoretical research to adapt them for technological use and enable various applications. The fact that these materials have a high transition temperature of 94 K and maintain good current-carrying capacity even under strong magnetic fields makes them a preferred choice for many uses. This study examines how 1% Ag substitution affects the overall properties of the NdBa₂Cu₃O_x superconducting system. The results show that Ag substitution did not significantly change the crystal structure of the base material. However, the superconducting transition temperature increased by 1.5 K, and the critical current density reached 4.9 x 10⁵ A/cm². Additionally, no impurities were detected in the structure due to Ag substitution, which also showed stabilizing effects concerning O₂ concentration. This is believed to further enhance the usability of Nd_0.9Ag_0.1Ba₂Cu₃Ox in high-tech applications.
