  • Synthesis approaches usually affect the physical and chemical properties of ferrites. This helps ferrite materials to design them for desired applications. Some of these methods are mechanical milling, ultrasonic method, micro-emulsion, co-precipitation, thermal decomposition, hydrothermal, microwave-assisted, sol-gel, etc. These methods are extensively reviewed by taking example of ZnFe2O4. These methods also affect the microstructure and local structure of ferrite which ultimately affect the physical and chemical properties of ferrites. Various spectroscopic techniques such as Raman spectroscopy, Fourier Transform Infrared spectroscopy, Ultra Violet-Visible spectroscopy, Mossbauer spectroscopy, extended x-ray absorption fine structure, and electron paramagnetic resonance are found helpful to reveal this information. Hence, the basic principle and the usefulness of these techniques to find out appropriate information in ZnFe2O4 nanoparticles is elaborated in this review.

  • A hydrated strontium iron fluoride, Sr2Fe2F10(H2O) has been synthesized and characterized. The material was synthesized through mild hydrothermal reaction using an aqueous CF3COOH solution. The material exhibits a one-dimensional structure consisting of chains of corner-shared Fe3+F6 octahedra, isolated Fe3+F5(H2O) octahedra, chains of SrF10 polyhedra and isolated SrF8 polyhedra, respectively. Magnetic property measurements on Sr2Fe2F10(H2O) reveals an antiferromagnetic order at TN of ~2.5 K with a Weiss temperature (θ) of -61.51 K.
