Figure 5

(a) EELS of main elements, La–M, Mn–L, Ba–M, Cu–L and O–K edges, across LCMO/YBCO/LCMO interfaces. (b) Different oxygen environment distributions obtained by least-squares fitting to the O–K edges. The EELS transition regions between LCMO and YBCO are highlighted for both interfaces. (c) Oxygen K edge spectra in different local chemical environments. In (b,c), green: LCMO; red: Cu–Oa (apical oxygen); blue: Cu–Ob (in-plane oxygen).
