Abstract

A multiferroic BiFeO₃ and YMnO₃ multilayer film was deposited on an SrTiO₃:Nb substrate using the pulsed laser deposition method. A large perpendicular exchange bias was observed, arising from the cycloid spin structure of the BiFeO₃. In addition, at room temperature the film displays a larger magnetic moment than BiFeO₃ and YMnO₃, as well as ferroelectricity with good retention capability. Large exchange biasing, controlled by the magnetic field cooling history, will introduce one more parameter into the magnetoelectric control of multiferroic multilayers.
