In this study, CuFeO 2 thin films were deposited onto quartz substrates using a sol–gel and a two-step annealing process. The sol–gel-derived films were annealed at 500°C for 1h in air and then annealed at 600 to 800°C for 2h in N 2 . X-ray diffraction patterns showed that the annealed sol–gel-derived films were CuO and CuFe 2 O 4 phases in air annealing. When the films...
