摘要

Iron tellurate–hematite nanocomposite was obtained by the thermal decomposition of organotellurium ferrocenecarboxylate. XRD study revealed that the composite has 68% tetragonal Fe2TeO6 phase and 32% trigonal α-Fe2O3 phase. Energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy confirm the chemical homogeneity of the nanocomposite. During the thermal decomposition of the precursor, tellurium segregates out in amorphous form resulting in a proportionate amount of α-Fe2O3 phase. Room temperature Mössbauer spectrum reveals that Fe is in +3 state in the nanocomposite. The bulk magnetization study reveals room temperature ferromagnetic order in the nanocomposite.
