抄録

Monoammoniated alkali fullerides salt (NH3)K3-xRbxC60 (0 ≤ x ≤ 3), forming an isostructural orthorhombic series followed by a Mott-Hubbard type antiferromagnetic transition. The Néel temperature TN was found to first increase with the interfullerene spacing and then decreases for (NH3)Rb3C60, forming a maximum at 76 K. This behavior can not be understood by a simple localized electron model and provides direct evidence for the important role of electron correlation effects.
