Exploring The Correlation Between Morphology And Magnetodielectric Properties In KBiFe2O5 -CoFe2O4 Composite

Abstract

In the age of machine learning and artificial intelligence, there is a need for a new multifunctional device that is lighter, faster, and more energy efficient. Due to the fascinating multiferroic characteristics of KBiFe2O5 and its composite with ferrite, it has attracted much attention, making it a viable material for various device applications, including sensors, actuators, memory, and other technological ones. In this study, we report the synthesis of (1-x)KBiFe2O5-(x)CoFe2O4 composite using a citric-assisted sol-gel method. X-ray diffraction (XRD) data confirms the phase formation of the prepared composite. Field scanning electron microscopy (FSEM) of the prepared composite reveals the presence of both types of grains of the parent material (KBiFe2O5 and CoFe2O4), confirming the successful formation of the composite phase. Magnetodielectric measurement confirms the enhanced coupling in the composite as compared to KBiFe2O5, which is attributed to the addition of ferrimagnetic CoFe2O4.
