Abstract

MEM nuclear density analysis from neutron diffraction data measured in situ at 1015.6 °C has indicated the two-dimensional network of curved O2-O3-O2 oxide-ion diffusion paths on the (Pr,La)-O layer in a K2NiF4-type structured oxide-ionic and electronic mixed conductor(Pr0.9La0.1)2(Ni0.74Cu0.21Ga0.05)O4+δ.
