Highlights: Black-Right-Pointing-Pointer Pulsed laser deposition is the promising technique for growing high quality single phase Fe{sub 3}O{sub 4}. Black-Right-Pointing-Pointer Crystal quality and magnetic properties of the Fe{sub 3}O{sub 4} films strongly depend on the substrate temperature during the growth. Black-Right-Pointing-Pointer Optimum of the substrate temperature leads high crystal quality of single phase Fe{sub 3}O{sub 4}. -- Abstract: Iron oxide films were grown on sapphire substrates by pulsed laser deposition at substrate temperatures between 100 and 700 Degree-Sign C. X-ray diffraction, Raman spectroscopy, and vibrational sample magnetometer analysis revealed that structural and magnetic properties of the iron oxide films strongly depend on the substrate temperature during growth. Single phase Fe{sub 3}O{sub 4} film was successfully grown on sapphire substrate at a substrate temperature of 500 Degree-Sign C. The saturation magnetic moment of the single phase Fe{sub 3}O{sub 4} film is 499 emu/cm{sup 3}, which is in good agreement with the value reported for bulk magnetite, suggesting the Fe{sub 3}O{sub 4} film is of high crystal quality without antiphase boundaries.
