The effective diffusion coefficient was determined by transient electrical conductivity measurements based upon Fick’s second law. The diffusion coefficient of La3+ ions was calculated from the effective diffusion coefficient. The diffusion coefficient of the La3+ ion, and the activation energy, were in agreement with reported value. The diffusion coefficient of holes was also calculated. The diffusion coefficient of holes was much higher than those of other components.
