FIG. 1.

(Color online) Structural analysis of typical films on Si (001) substrates. (a) X-ray diffraction. (b) In-plane piezoforce microscopy image shows the presence of all four in-plane polarization variants in these BFO films. (c) Transmission electron microscopy image.

FIG. 2.

(Color online) Typical magnetic properties for bilayer CoFe/BFO heterostructures. (a) Magnetization hysteresis loops reveal large negative exchange bias. (b) Repeated magnetic cycling results in very little change in the magnetic properties. (c) Exchange bias field and coercive field as a function of magnetic cycle—no training effect is observed.

(Color online) Spin valve structures based on heterostructures. (a) Schematic illustration and scanning transmission electron microscopy image (b) Magnetic hysteresis loops of spin valve structures. (c) Current-in-plane magnetoresistance measurements.
