Magnetic spin structure and magnetoelectric coupling in BiFeO3-BaTiO3 multilayer

Magnetic spin structures in epitaxial BiFeO3 single layer and an epitaxial BaTiO3/BiFeO3
multilayer thin film have been studied by means of nuclear resonant scattering of synchrotron
radiation. We demonstrate a spin reorientation in the 15 x[BaTiO3/BiFeO3] multilayer compared
to the single BiFeO3 thin film. Where as in the BiFeO3 film, the net magnetic moment m→ lies in the (1–10) plane, identical to the bulk, m→ in the multilayer points
to different polar and azimuthal directions. This spin reorientation indicates that strain and interfaces play a significant role in
tuning the magnetic spin order. Furthermore, large difference in the magnetic field dependence of
the magnetoelectric coefficient observed between the BiFeO3 single layer and multilayer can be
associated with this magnetic spin reorientation.
