- 論文の詳細を見る
The ordered double perovskite oxide, Sr2FeMoO6, has a half-metallic property and is considered as one of the best materials for creating spin-polarized current for next-generation spintronics devices. In order to optimize the fabrication conditions for (001)-oriented single-crystalline Sr2FeMoO6 thin films, a combinatorial pulsed laser deposition (PLD) technique, together with combinatorial (high-throughput) characterization, were carried out. It is found that atmospheric pressure during the deposition affects the formation of secondary phases, thus careful control of this parameter is necessary. On the other hand, substrate temperature affects the electric transport property and surface flatness; better results are obtained at a higher substrate temperature.
