11. When the lattice mismatch between the film and the substrate is too large a layer is formed with large internal stress from the substrate in the initial stage of film growth. However, after the layer was grown up to some critical thickness, the resultant lattice distortion is almost released by dislocations and defects. Further film growth is stress-free, resulting in a layer with a lattice constant inherent to the film. Thus, the double layered film shows two lattice constants, i.e., two x-ray reflection peaks.

13. The difference in magnitude between the spectra is caused by Fe concentration in the films different from the nominal value, not substantial in this discussion.
14. This effect represents that the energy position of the d band moves, sensitively depending on the strength of electron-electron repulsion between a rare earth ion and its surrounding anions. See the reference: L. G. Van Uitert, J. Lumin. 29, 1 (1984).
