The magnetic properties of the polymerized phase of RbC60 have been investigated by static magnetization measurements. The magnetic susceptibility comprises a temperature dependent part that decreases rapidly below 50 K, where the metal-insulator transition and the subsequent antiferromagnetic ordering are expected according to electron spin resonance results. The temperature variation of this contribution resembles that of quasi-one-dimensional gapped systems and shows substantial field dependence suggesting a disordered antiferromagnetic phase.
