Abstract :
Epitaxial thin films of ABO3 (A=Ca, Sr; B=3d,4d transition metal) were fabricated on a (100)-SrTiO3 substrate by spin coating an organic metal and subjecting it to successive heat treatments. Results of X-ray 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 that its pseudocubic axes align parallel to the cubic axes of the SrTiO3 crystal. Epitaxial ABO3 thin films have similar transport and magnetic properties to those of bulk materials.
