A Sr2FeMoO6 (SFMO) pellet was synthesized to use as a target in the Pulsed Laser Deposition (PLD) chamber. The method chosen was a solid state reaction of SrCO3, Fe2O3 and MoO3. All three materials were combined stoichiometrically, ground in a ball mixer, and annealed for 36 hours at 1000°C. A pellet press was custom designed and used to press the annealed powders into a pellet. The magnetic and structural properties of the powder were studied using a Quantum Design MPMS SQUID magnetometer and powder X-Ray diffractometer, respectively. Previous studies of bulk SFMO suggest it to be ferrimagnetic or ferromagnetic, with a magnetic ordering near 400K. The magnetization data completely agrees with the reported data. The 1” diameter pellet was used as a target in the PLD chamber to grow a 200 nm thin film on a SrTiO3 (001) substrate at 800°C and 10-6 torr. X-Ray diffraction was performed on the film to ensure it was epitaxially oriented. From this data, calculations were performed which found the thin film to have been grown epitaxially.
