Spray-pyrolysis deposition of LaMnO3 and La1 xCaxMnO3 thin films

Ethylene glycol solutions of La–Mn(II) and La–Ca–Mn(II) citric complexes has been used as a starting material for spraypyrolysis deposition of LaMnO3 and La1 xCaxMnO3 thin films on b-quartz, fused quartz, Si(0 0 1) and SrTiO3(1 0 0) substrates heated during the deposition at 380 8C. At suitable post-deposition heating conditions highly uniform films, 0.1–1 mm in thickness, with good crystal structure were obtained. Highly textured LaMnO3 films are obtained on SrTiO3(1 0 0) substrate. Interaction between the layer and Si-containing substrates is observed during the post-deposition heating in static air.
