Abstract An effective attractive Hubbard model is applied to explain the observed non-Korringa relation in doped fullerenes, which leads to a reduced Pauli susceptibility. The results basically agree with the experiments for K₃C₆₀, Rb₃C₆₀ and RbCs₂C₆₀. It implies that the pair correlation on site possibly plays an important role in the normal state for doped fullerenes.
