Abstract :
Epitaxial thin films ABO3 (A = Ca, Sr; B = 3d, 4d transition metal) were fabricated on the (100)-SrTiO3 substrate by spin-coating an organic metal, and subjecting it to successive heat treatments. Results of X-ray diffraction, reflection high-energy electron diffraction, and transmission electron microscopy indicate that the growth is pseudomorphic and the [00l] axis of the ABO3 film is perpendicular to the (100) plane of the SrTiO3 substrate and its pseudocubic axes align parallel to those of the SrTiO3 crystal. The epitaxial ABO3 thin films have similar transport and magnetic property to those of bulk materials.
