WebbJust after the publication of the Higuchi and Nagasawa paper, Shannon and Prewitt (1969) pro¬ posed a purely empirical and internally consistent set of ionic radii. A small revision was made soon after the appearance of the original set (Shannon and Pre¬ witt, 1970). WebbThe crystal structure of La(Mg2/3Nb1/3)O3 has been analyzed by high-resolution transmission electron microscopy (HRTEM) and Rietveld refinement using X-ray and neutron powder diffraction patterns.
