Abstract

Magnesium fulleride Mg₄C₆₀ was synthesized by a solid state reaction and assigned a rhombohedral structure with a = 9.99 Å, α = 55.1° from X-ray diffraction measurements. The electrical resistivity measurement of the Mg_xC₆₀ film showed its non-metallic character. The magnetic susceptibility of Mg₄C₆₀ was investigated with ESR and SQUID measurements. From the absence of Pauli paramagnetism in the ESR measurement, Mg₄C₆₀ was revealed to behave as a non-magnetic insulator. Large core diamagnetism was detected by SQUID measurements.
