Chemical solution processing and properties of Sr2FeMoO6 thin films

Crack-free and oriented Sr2FeMoO6 (SFMO) thin film with double perovskite structure has been fabricated by the chemical solution deposition (CSD) method. A homogeneous and stable SFMO precursor solution was successfully prepared by controlling the reaction of starting metal-organic compounds in a mixture solvent of 1-propanol and 2-methoxyethanol. SFMO thin films with c-axis preferred orientation could successfully be synthesized on MgO (0 0 1) and SrTiO3 (0 0 1) substrates by optimizing the several processing conditions. SFMO thin film prepared on SrTiO3 (0 0 1) showed a magnetoresistance effect at a low magnetic field.
