The diffusion of positive muon $$mu^+$$ in condensed matter has been investigated for many years by using $$mu^+$$ spin rotation/relaxation ($$mu^+$$SR) technique. The $$mu^+$$SR studies have provided deep insight into quantum diffusion at low temperatures as well as hopping process at high temperatures, which are closely related to hydrogen dynamics in the dilute limit. We here report transverse field (TF) $$mu^+$$SR studies of the $$mu^+$$ diffusion in cubic $$f$$-electron compounds PrPb$$_3$$ and SmAg$$_2$$In. The $$mu^+$$ site splits into two magnetically labeled sites when high TF is applied to single-crystalline specimens along the [001] direction. The $$mu^+$$SR lines show drastic variation according to the $$mu^+$$ motion between the magnetically labeled sites. From detailed analysis of the $$mu^+$$SR lines, we deduced $$mu^+$$ hopping parameters for both compounds.
