Abstract
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.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
