Exploring BiFeO3 /Fe3O4 nanocomposite for possible application in magnetic hyperthermia

The development of perovskite/spinel nanocomposite BiFeO3/Fe3O4 (BFO/FO) holds particular interest for applications in magnetic hyperthermia therapy (MHT). This work offers a significant avenue for advancing material properties and evaluating the heating efficiency, considering the impact of structure, and magnetic characteristics within the perovskite/spinel system. A sol-gel synthesis process for phase-pure BiFeO3 production was successful, which is subsequently utilized with Fe3O4 to form a nanocomposite (BiFeO3)1_x/(Fe3O4)x. Our findings indicate that increasing the concentration of Fe3O4 in the nanocomposite enhances the saturation magnetization and the specific absorption rate (SAR). Importantly, the addition of BiFeO3 to Fe3O4 further enhances the nanocomposite's heating efficiency. This study underscores the potential of perovskite/spinel nanocomposites in realizing advanced materials with tailored properties and multifaceted functionalities.
