Abstract

Bi Fe O 3 and Bi1−xGdxFeO3 (BGFO) (x=0.03, 0.05, 0.07, 0.10, and 0.15) thin films were deposited on Pt∕Ti∕SiO2∕Si substrates using a metal organic decomposition process. X-ray diffraction results show that a gradual phase transition from rhombohedral to pseudotetragonal structure may occur in BGFO films with the increase of Gd content. Due to the lower leakage currents resulting from the smaller grain sizes and smoother surfaces, well saturated P-E hysteresis loops, which show weak dependence of frequency in the range of 3–50kHz, can be observed in all BGFO films at room temperature. The remanent polarization for BGFOx=0.03 film is about 79μC∕cm2. In addition, no evident fatigue can be observed after 109 switching cycles.
