Abstract

Tb and Co substituted bismuth ferrite nanoparticles (NPs) with chemical composition Bi_1-xTb_xFe_1-yCo_yO₃ (x = 0, 0.05; y = 0, 0.05) have been synthesized by a sol-gel method and characterized by x-ray diffraction (XRD), Mossbauer spectroscopy, dc magnetization and electric polarization measurements. The aim of the present work is to improve ferroelectric properties of BiFeO₃ by substitution of Tb³⁺ ions in Bi³⁺ site and magnetic properties by substitution of Co²⁺ in Fe³⁺ site. The XRD patterns of all prepared samples show formation of the desired phase along with a small amount of impurity. Room temperature Mossbauer spectroscopic studies reveal that all samples are in magnetically ordered state. Magnetic hysteresis loops of all samples indicate a significant enhancement of magnetic moment and coercivity whereas electric polarization measurements at room temperature reveal an improvement of ferroelectric properties in the co-substituted sample.
