摘要：

The zero-field muon-spin-relaxation (ZF-mu+SR) technique provides direct observation of the development of antiferromagnetic long range order in the hyperexpanded methylaminated fulleride salt, (CH3NH2)K3C60 below T-N similar to 10 K coherent ordering of the electronic magnetic moments leads to a local field of similar to 25 G at the muon site at 1.2 K.
