Inhaltsangabe:
- The dynamical Kubo-Toyabe (dKT) function is extended to describe the spin relaxation under the coexisting dynamical and static internal magnetic fields. A detailed re-evaluation of the previous $μ^\pm$SR data in Na$_x$CoO$_2$ using this function disfavors the conventional interpretation based on sodium-ion diffusion and instead supports the $μ^+$ self-diffusion scenario. This also resolves the long-standing inconsistencies in the dKT-function-based $μ$SR studies on ion diffusion from the viewpoint of classical over-barrier-jump mechanism.
