The recent great fundamental and technological interest for interfaces in thin films of correlated oxides (manganites, aluminates, titanites and cuprates) is caused by two main reasons: 1) to stabilize the bulk-like magnetism, metallicity and ferroelectricity in ultrathin films and 2) to create new interface-originated properties not akin to the bulk phases. We investigate thin ferromagnetic manganite films with various interface modifications grown by metalorganic aerosol deposition (MAD) technique on SrTiO3 substrates with different orientations. Structure and morphology is studied by AFM/STM, XRD, XRR and HREM; transport and magnetization by PPMS and MPMS, respectively. We observe ferromagnetic metallic behavior of a three unit cell thick interface engineered lanthanum manganite film, modified by 2 u.c. of strontium manganite, grown on STO(100). Financial support from EU FP 7, IFOX (interfacing oxides) project is acknowledged.
