Development of faster, smaller and less energy consuming devices led to new concept of electronics called spintronics. Spintronics are based on properties of electrons and associated magnetic moments. Promising materials which can follow this concept are materials based on lanthanum manganite (LaMnO3). LaMnO3 is specific due its magnetoelectric properties such as giant magnetoresistance (GMR) and multiferroic behaviour. Also, perovskite structure of LaMnO3 is very sensitive to external stimuli and ions substitution which gives possibility of phase control and fast manipulation of electric and magnetic properties. Ultrathin epitaxial films are conventionally obtained from gas phase, utilizing sophisticated equipment and a lot of energy. Following the trend of devices miniaturization, this form of material is very desirable. The aim of this work was obtaining epitaxial thins film based on LaMnO3 / La1-xSrxMnO3 from liquid phase. Polymer assisted deposition (PAD) technique was used as syn...thesis method. LaMnO3 / La1-xSrxMnO3 solutions were prepared by dissolving of La(NO3)3·6H2O and Mn(NO3)2·4H2O in the distilled water, while strontium nitrate was used as a source of Sr2+ ions. Polyethileneimine and EDTA were added to stabilize aqueous solution of precursors Prepared solutions of polymer and precursors were deposited on single crystal SrTiO3 (001) substrate in order to achieve highly oriented growth. Deposited films were thermally treated up to 900 °C. After the annealing process, structural characterization was performed by XRD and HR-TEM, while functional properties were investigated by magnetic measurements
