| Abstract: | BiFeO3(BFO) film was grown on ITO/glass substrate by chemical solution deposition method. Structure, surface morphology, valence, magnetic property and ferroelectricity of the BFO film were investigated by X-ray diffractometer, scanning electron microscope, X-ray photoelectron spectroscopy, magnetic property measurement system and ferroelectric tester. The results showed that the film growed along [101] crystal orientation and had a plat and smooth surface. The films presented ferromagnetic behavior, the magnetization easy axis is along [101]. The saturation polarization was about 51.3 μC/cm2. |
