FIG. 1.

(Color online) XRD diffraction patterns of the (001) STO substrate, BFO single-layered films, and Fe3O4/BFO heterostructures.

(Color online) XRD θ–2θ scans for single-layered films and heterostructures: (a) x-ray rocking curve (ω–θ scan) of (001) reflection of the BFO layer with (top panel) and without (bottom panel) Fe3O4 films; (b) φ–scan of the (220) reflection of the Fe3O4 film deposited on BFO layer; (c) pole figure of the epitaxial BFO single films of (222) reflection; (d) pole figure of the BFO layer of (222) reflection in bilayer.

FIG. 3.

(Color online) Magnetization loops at T = 5 K for three typical samples. The inset shows typical M–H loops of the Fe3O4/BFO (22 nm) heterostructures measured with two different vibrating sample magnetometers for comparison.

FIG. 4.

(Color online) (a) Total magnetic moments of different samples measured at 5 K as a function of t BFO; (b) magnetic moment of the Fe3O4/BFO heterostructures subtracting the contribution of Fe3O4 films with error bars. The triangle connection line is the contribution of the BFO single layer; (c) schematic of the interface coupling effect.
