Abstract

We investigated the growth characteristics and multiferroic properties of BiFeO ₃ (BFO) and Yb-doped BiFeO ₃ (Bi _0.85 Yb _0.15 FeO ₃ , YBFO) thin films grown on Pt/Ta/glass substrates. X-ray diffraction experiments showed that both BFO and YBFO thin films had preferentially (111)-oriented polycrystalline structures. Yb doping of BFO thin films led to enhanced multiferroic properties in terms of the ferroelectricity (remanent polarization of about 41.5 μC/cm ² ) and ferromagnetism (remanent magnetization of about 1.91 emu/cm ³ ). According to piezoresponse force microscopy experiments, the YBFO thin films possessed larger ferroelectric domain structures than the BFO thin films due to the higher domain wall energy of the YBFO thin films.
