Development and characterization of nano-multifunctional materials for advanced applications

Multifunctional zinc oxide-bismuth ferrite and tin dioxide-bismuth ferrite have been synthesized using a double precipitation technique. The structural formation, chemical composition, morphology and thermal properties were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy with energy dispersive spectroscopy and transmission electron microscopy. Temperature-dependent magnetic behaviour of zinc oxide-bismuth ferrite and tin dioxide-bismuth ferrite were studied using a vibrating sample magnetometer in the range of 5 K to 300 K. The results indicate that zinc oxide-bismuth ferrite is a potential candidate for spintronics applications.
