Alkali metals (A = K, Rb, Cs) intercalated fullerene A₃C₆₀ has great potential as an applied material due to its relatively high superconducting transition temperature (~30 K), high upper critical field (~900 kOe), and isotropic superconducting properties. However, previously reported synthesis methods have faced challenges in bulk superconducting material production, such as complex processes and lengthy synthesis times. In this presentation, we will report on a rapid and scalable fabrication method for bulk A₃C₆₀ superconductors.
