EPITAXIAL NATURE OF THE FILMS OF LANIO3, PB(ZR0.5TI0.5)O-3, AND LA0.95MN0.95O3 OBTAINED BY NEBULIZED SPRAY-PYROLYSIS

Films of complex oxide materials deposited on single-crystal substrate s by means of nebulized spray pyrolysis have been investigated for the ir 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 demonstr ated that films of metallic LaNiO3, ferroelectric Pb(Zr0.5Ti0.5)O-3, a nd La0.95Mn0.95O3 exhibiting giant magnetoresistance, deposited by neb ulized 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.
