Abstract

We report ZF μSR measurements in Cs1C60 at low temperature and LF μSR in the superconductor Rb3C60. In Cs1C60, the internal magnetic field distribution is broad and static, and the relaxation at 1.9 K resembles that of a spin density wave. In Rb3C60, we observe a strong field dependence to the coherence peak in the LF relaxation rate of endohedral muonium (Mu@C60) at anomalously low field and a residual low temperature relaxation.
