Abstract
We have prepared a series of (PLZT)x (BiFeO3)1-x transparent thin films with thickness of 300 nm by a thermal pyrolysis method. Only films with x % 0:10 formed a single phase of perovskite structure. The film where x 1⁄4 0:10 exhibited both
ferromagnetic and ferroelectric properties at room temperature with spontaneous magnetization and coercive magnetic fields of 0.0027 m B and 5500 G, respectively. The remanent electric polarization and coercive electric field for the film where x=0.10 were 3.0 mC/cm 2 and 24 kV/cm, respectively. Additionally, films with 0:02<=x<=0.10 showed both magneto-optical effects and the second harmonic generation of transmitted light.
