In our previous work, we evaluated the intergranular current density of sintered Rb₃C₆₀ bulk using a method that allows for large-scale and high-speed synthesis, and reported at JSAP EXPO Autumn 2025. Currently, for fullerene-based superconductors, Cs-doped compounds are believed to have the highest superconducting transition temperature Tc. In this study, aiming to achieve high T_c, high H_c2, and high intergranular current density, we substituted Cs into Rb₃C₆₀. In this presentation, we will report on the parameters obtained through this substitution, the optimization of synthesis conditions to achieve high J_c, and a comparison with the results for Rb₃C₆₀.
