We report on the controlled multiphase thin film growth in the Bi– Fe– O system. By varying the deposition oxygen pressure, the dominant phase formed in the film continuously changes from ferroelectric BiFeO 3 to a mixture of ␣-Fe 2 O 3 and ferromagnetic ␥-Fe 2 O 3. X-ray diffraction and high-resolution transmission electron microscopy have revealed that(More)
