Effects of rare earth manganite on structural, magnetic and ferroelectric properties of BiFeO3 thin films — •Abdelilah Lahmar, Salah Habouti, Matthias Dietze, Claus-Henning Solterbeck, and Mohammed Es-Souni — Institute for Materials and Surface Technology, University of Applied Sciences Kiel, Germany

The results of structural studies of pure-phase perovskite thin films of BiFeO3 – 10% RMnO3 (R= La, Eu, Gd, Tb and Dy) are presented. Raman Scattering studies show lines broadening similar to what is reported for RMnO3; they were attributed to Jahn-Teller distortion and orthorhombic structural change. Evidence of an anomaly of the orthorhombic distortion at GdMnO3 could be obtained. Interestingly the addition of GdMnO3 leads to a substantial increase in magnetization, combined with moderate ferroelectric polarization. All other compositions are characterized by higher ferroelectric polarization but almost no magnetization.
