Abstract Precise electron spin resonance (ESR) spectroscopic studies have been done for K x C 60 . Three ESR peaks corresponding to the three important crystal phases of K x C 60 (face-centered cubic K 3 C 60 , body-centered tetragonal K 4 C 60 , and body-centered cubic K 6 C 60 ) are reported. From the temperature dependencies of the ESR intensity for these three phases, it is confirmed that the superconducting K 3 C 60 phase is metallic, and that both of the non-superconducting K 4 C 60 and K… CONTINUE READING
