Epitaxial nature of the films of LaNiO<SUB>3</SUB>, Pb(Zr<SUB>0.5</SUB>Ti<SUB>0.5</SUB>)O<SUB>3</SUB>, and La<SUB>0.95</SUB>Mn<SUB>0.95</SUB>O<SUB>3</SUB> obtained by nebulized spray pyrolysis

Films of complex oxide materials deposited on single-crystal substrates by means of nebulized spray pyrolysis have been investigated for their epitaxial nature by employing X-ray rocking curve studies and high-resolution electron microscopy, the latter enabling a direct study of the interface between the film and the substrate. It has been demonstrated that films of metallic LaNiO3, ferroelectric Pb(Zr0.5Ti0.5)O3, and La0.95Mn0.95O3 exhibiting giant magnetoresistance, deposited by nebulized spray pyrolysis on SrTiO3(100) or LaAlO3(100) are all epitaxial. Nebulized spray pyrolysis is a valuable inexpensive tool to deposit epitaxial films of complex oxide materials
