Table 1 Crystal structure and lattice parameter of STO (ref.45), KTO (ref.46), LAO (ref.47), DSO (ref.48), LSAT (ref.53), and LSAO (ref.54) substrates, and the in-plane lattice mismatch between LNMO (ref.52) and various substrates, which is calculated by using the equation of Δf = (af − a0)/a0 * 100% (a0 and af are the lattice parameter of substrate and pseudocubic LNMO, respectively).
