Abstract
ABSTRACT Recently, multiferroic materials such as BiFeO3 have fascinated researchers for their potential application in memory storage devices. However, high leakage, weak magnetism and magnetoelectric coupling in this system restrict its practical applications. To solve this, the octahedra tilt influencing electrical, magnetic and thermal properties of polycrystalline Bi0.9Co0.1FeO3 ceramics via solid state route is studied here. Cobalt doped BiFeO3 affect the structural arrangement and tunes the crystal engineering of BiFeO3. In particular, the temperature-dependent dielectric behaviour of Bi0.9Co0.1FeO3 shows a significant dielectric anomaly corresponding to the magnetoelectric coupling in this sample. Further, the maximum magnetization of Bi0.9Co0.1FeO3 is 8.70 emu/ g which is two orders higher in magnitude compared to pristine BiFeO3.
