摘要：

High-valence Pr-doped BiFeO3 (BPF) multiferroic thin film was prepared by pulsed laser deposition on a Pt/TiO2/SiO2/Si substrate. X-ray diffraction analysis indicates that the BPF film is of pure phase with a polycrystalline perovskite structure. The BPF film exhibited enhanced multiferroic properties: (i) a rectangular-shaped electric hysteresis loop with a large P-r of 75 mu C/cm(2) and a low E-c of 250 kV/cm at E-max similar to 620 kV/cm, (ii) a saturated magnetic hysteresis loop with a large M-s of 58 emu/cm(3), and (iii) a fatigue-free behavior after being subjected to 1.2x10(9) switching cycles, which were superior to, in some aspects, those of La- or Nd-doped BiFeO3 films reported before.
