6.3 $\mu {\cal SR}$ in the Magnetic State of A₁C₆₀

In this section, results of measurements on the low temperature magnetic phase of A₁C₆₀ for A = Rb and Cs are presented. The observed depolarization is discussed, and a phenomenological form is used to parametrize the relaxation, so that its temperature (and field) dependence can be conveniently summarized. All discussion of the results, however, is deferred to the following section. Note that because of the large size of the bound electron moment, the contribution of muonium (discussed in the previous section) to the ZF or TF spectra in the magnetic state will simply be an exceedingly fast relaxating signal, which will only be observed as a missing fraction.
