Processing and characterization of LaMnO3-buffered layer on IBAD-MgO template

Using two different IBAD-MgO templates with the in-plane textures of ∼8.5° and ∼6.5° for MgO (2 2 0), respectively, we tried to identify the correlation between the LaMnO 3 (LMO) buffer layer and IBAD-MgO template and also to optimize the PLD processing conditions for the LMO layer. Better in-plane texture of the LMO buffer layer less than 7° was obtained from the IBAD-MgO template of ∼6.5° in-plane texture over almost all deposition temperature and time, supporting that the processing window is very wide, although the in-plane texture of LMO buffer layers was somewhat sensitive not only to deposition temperature but also to deposition time (or layer thickness). Optimally processed LMO buffer layer at deposition temperature of 775 °C in P O 2 of 100 mTorr for 10 min exhibited the Δ φ value of 5.2°.
