About the book
Magnetic MFe2O4 (M = Mg, Mn, Li,Fe, Co, Ni, Cu and Zn) transition metal based spinel oxides are multifunctional materials; especially ferrite based insulating magnetic oxides are widely studied. Since last decade or so, metal-oxide nanoparticles are widely studied due to their unique properties which include: optical, electronic and magnetic properties. In particular, spinel ferrites received much attention in research and development and as well as in industrial community due to their remarkable electrical, magnetic, magnetoelectric and electrochemical properties, to be effectively utilized in various technological applications especially in electronic, automobile (automotive cathode based Li-ion batteries), aerospace industries. Also magnetic spinels ferrites are also suitable for stress and torque sensor applications due to their magnetic susceptibility. Applications of magnetic spinels include but are not limited to high density magnetic data storage, sensors, magnetic resonance imaging, ferrofluids technology, biocompatible magnetic nanoparticles for cancer treatment, magneto-optical devices and magnetostrictive component of the torque sensor for power-steering systems in automotive industries, wireless communications etc.
Here in this project we will mainly concentrate on synthesis methods (conventional synthesis, nanoparticles, sol-gle, solvothermal, co-precipitation, hydrothermal etc.) of transition metal based magnetic spinel oxides and their structural property relations, which include X-ray diffraction, Raman spectroscopy, SEM,TEM, spinel, inverse spinel structure. We will also discuss dielectric, magneto-dielectric optical, magnetic, magnetostrictive, multiferroic properties of transition metal based magnetic spinel oxides. Finally, we will also put emphasis on various properties of magnetic spinels for both cathode and anode based Li-ion batteries.
