Abstract
$BiFeO_3$ (BFO) thin films were deposited on Pt/Ti/$SiO_2$/Si(100) substrates by RF magnetron sputtering method at room temperature. The influence of the flow rate of $O_2$ gas on the preparation of $BiFeO_3$ thin films was studied. XRD results indicate that the $BiFeO_3$ thin films were crystallized to the perovskite structure with the presence of small amount of impurity phases. The flow rate of $O_2$ gas has great affect on the microstructures and magnetic properties of $BiFeO_3$ thin films. As flow rate of $O_2$ gas increased, roughness and grain size of the thin films increased. $BiFeO_3$ thin films exhibited weak ferromagnetic behavior at room temperature. The PFM images revealed correlation between the surface morphology and the piezoresponse, indicating that the piezoelectric coefficient is related to microstructure.
