Muon spin rotation (..mu..SR) has been used to probe the dynamics of rare-earth ions in situations where the crystal field splittings have important effects. This paper outlines the theory of spin dynamics in such cases and discusses its application to ..mu..SR studies in two specific systems: erbium in noble metals and holmium in LuRh/sub 4/B/sub 4/. The former shows novel effects of a muon-induced axial crystal field in the otherwise cubic lattice, and the latter exhibits a dramatic change in temperature dependence because of small admixtures from the tetragonal field.
