    • An estimate of the reduction of the hopping rate k due to configurational degeneracy can be done in following way. The Sr atom can jump to another basin only if it is located in front of corresponding path. Since the energy difference between 1 and 2 sites is small (Δ Eintra=0.1 eV ), we can assume for simplicity that at room temperature, the Sr atom can be found at any location along the basin with equal probability. Hence, the fraction of time that the Sr atom spends in front of the corresponding path is k=W/L, where W stands for the width of corresponding migration path and L is length of basin loop.
