Temperature-dependent electrical, elastic and magnetic properties of solgel synthesized Bi 0.9Ln 0.1FeO 3 (Ln=Nd,Sm)

Journal Article


Abstract


  • This report details correlated electrical, mechanical and magnetic behaviour in BiFeO3

    ceramics doped with 10% Ln (Ln D Sm, Nd) ions on the Bi, or perovskite A, site and

    synthesized by a sol–gel method. The ceramics exhibit bulk piezoelectric and ferroelectric

    properties and clear ferroelectric domain patterns through piezoresponse force microscopy.

    Resonant ultrasound spectroscopy, dielectric spectroscopy and magnetometry studies show

    correlated magnetoelectromechanical behaviour and the existence of weak ferromagnetism for

    both compositions. An anomaly with simultaneous mechanical and magnetic signatures is

    discovered in both materials near room temperature, while previously reported transitions and

    anomalies are found to exhibit electro- and/or magnetomechanical coupling. Magnetism is

    significantly enhanced in the Sm doped sample, which is a promising multiferroic material.
