Reduced ferroelectric coercivity in multiferroic Bi 0.825 Nd 0.175 FeO 3 thin film
Bi 0.825 Nd 0.175 FeO 3 ĶBNFOĶ thin film is grown on Pt/ TiO 2 / SiO 2 / Si substrate by pulsed laser deposition, and its multiferroic properties are compared with those of BiFeO 3 ĶBFOĶ thin film. With limited Fe 2+ ions and its twinborn oxygen vacancies, both samples show low dielectric losses of Ļ½0.026 at 100 Hz and high maximum ferroelectric polarizations of Ļ³34 C/cm 2 . The ferroelectric coercive field of BNFO is reduced by Ļ³40%, reaching a low value of 235 kV/ cm, compared to that of BFO due to the increased ratio of 180Ā°and curved ferroelectric domains to total ferroelectric domains and better nucleation of the ferroelectric domains at the BNFO/Pt interface. The Raman scattering spectra confirm that the ferroelectric polarizations of both samples originate in the stereochemical activity of the Bi lone electron pair. Weak ferromagnetism is observed in both samples as a result of the limited amount of Fe 2+ ions and ā„-Fe 2 O 3 impurity
