PREPARATION OF EPITAXIAL LA1-XSRXMNO3 FILMS ON SRTIO3(001) BY DIPPING-PYROLYSIS PROCESS

La1-xSrxMnO3 (LSMO) (x = 0-0.3) films were prepared on SrTiO3(001) sub strates by the dipping-pyrolysis process using metal naphthenates as s tarting materials. Epitaxially grown LSMO films were obtained by heat treatment at 800-1200 degrees C; the fluctuation of alignment of these films, evaluated by reciprocal-space mapping of asymmetric x-ray diff raction, was markedly small, as comparable to that of the substrates. The LSMO films with x = 0.1-0.3 showed metallic conduction behavior at 25-300 K, and the resistivity was as low as that of LSMO single cryst als, e.g., 4.5 x 10(-4) Omega . cm at 150 K for the film with x = 0.3.
