films were grown by a pulsed laser deposition method. In the cross-sectional transmission electron microscopy observation, the presence of nanorods with 10nm average diameter was confirmed from bright-field images, and these nanorods in turn contained tin (Sn), as confirmed from the energy-dispersive X-ray spectroscopy spectra. The crystal structure of the nanorod was determined to be cubic perovskite from its selected area electron diffraction pattern. Using the selected area electron diffraction patterns, the lattice constant of the nanorods in the ErBa
