摘要

We report ferroelectric (FE), ferromagnetic, and magnetoelectric (ME) properties of BiFeO 3 films directly deposited on flexible magnetic Ni tapes. Without use of metal-oxide and/or noble metal buffer layer between the BiFeO 3 and the Ni, both ferroelectric and magnetic properties of the film and the substrate are preserved. X-ray diffraction and transmission electron microscopy analyses confirm the formation of preferentially oriented (110) BiFeO 3 film on Ni tapes. The BiFeO 3 film has a saturation polarization and a piezoelectric d 33 coefficient of 69 μC/cm 2 and 52 pm/V, respectively. The BiFeO 3 /Ni tape shows a magnetoelectric coefficient of 3.5 mV/cm·Oe.
