摘要：
We report an investigation of the magnetic properties of orthorhombic RbC60 using muon-spin rotation (mu SR). Measurements in zero applied field and high transverse field reveal a transition to a magnetic state below T=60 K. The mu SR spectra at low temperatures indicate that the internal magnetic fields are quasistatic on the time scale of a few mu s and have a Lorentzian-like distribution. These observations suggest that the magnetic structure is more disordered than a simple spin-density-wave state or an antiferromagnet.
