As electronic devices become more integrated in everyday life, there is an increasing necessity for miniaturization with exceptional efficiency. The use of tunable magnetic materials for information storage and transfer can meet this demand with many significant advantages over current technologies. The implementation of this science is contingent on optimizing the voltage control of magnetism (VCM), which has additional applications in healthcare and sensing. This work seeks to improve VCM in multiferroic composites and magnetoioics. In chapter 3 of this thesis, we report a straightforward and scalable synthesis of superparamagnetic cobalt ferrite nanoparticles that allows for precise size selection. The particles produced via this route also have remarkable size and shape uniformity, making them ideal for use in a strain-mediated multiferroic composite. In chapter 4 we advance fundamental understanding toward achieving unprecedented magnetic control in nanostructured Sm-Co magnets via electrochemical hydrogen charging. The structural and magnetic properties of SmCo5 and Sm2Co17, as well as the kinetics and thermodynamics involved in their hydrogenation, are documented for future work. Oxidation in air and in electrolyte is identified as a key challenge.

Magnetic spinels including ferrites are insulating magnetic oxides and chalcogenides with strong coupling to microwave frequencies and low eddy current losses making them indispensable for applications in wireless communications. The 13 chapters and preface of this book discuss other potential applications of magnetic spinels along with various methods used for their synthesis and their varied properties resulting from substituting different metal ions at the A and B sites. These applications include ferrofluids, anticorrosion coatings, absorber coatings for photothermal conversion, biomedicine, and environmental applications such as oxidation of volatile organic compounds and removal of arsenic and heavy metals from water. Emphasis is placed on structure-property correlations and on the nature of magnetism in spinels and their nanoparticles with current information provided for future research.

The title "Nano Biotechnology for Biomedical and Diagnostics Research" will address research aspects related to nanomaterial in imaging and biological research, nanomaterials as a biosensing tool, DNA nanotechnology, nanomaterials for drug delivery, medicinal and therapeutic application and cytotoxicity of nanomaterials. These topics will be covered by 16 different manuscripts. Amongst the authors that will contribute to the book are major scientific leaders such as S. Weiss - UCLA, I. Willner, and G. Golomb – HUJI, S. Esener - UCSD, E.C. Simmel - Tech. Univ. Munchen, I. Medintz – NRL, N. Hildebrandt - Université Paris and more. The manuscripts in the book intend to present specifically biological, diagnostics and medical problems with their potential solution by nano technology or materials. In this respect this book is unique, since it would arise from the biological problems to the nano technology possible solution and not vice versa.

This book has given an overview of the sol-gel auto-combustion preparation method and characterization of Ni0.5Co0.5FeCrO4. This work focused on the structural properties XRD,TGA, SEM, TEM, FTIR, Magnetic Properties, Dielectric Properties were measured.By using the TG curve the exact temperature of formation of ferrite phase was obtained.The properties such as dielectric constant, dielectric loss tangent as a function of frequency and temperature. The addition of chromium in nickel – cobalt ferrite significantly changes the electrical and magnetic properties. Nickel and cobalt ferrites are inverse ferrites and hence for x £ 1, nickel ferrite shows structure of inverse spinel and for x >1, the inverse structure converted into normal structure. The crystal structure of ferrite, cation distribution, synthesis route, sintering conditions, amount and type of impurity addition decides the electric and magnetic properties of ferrites. Same ferrite with different crystalline size shows different properties. The electrical and magnetic properties even structural properties of ferrites at nano-crystalline phase shows significantly difference than the bulk one. In the present investigation we have presented the results on structural and magnetic properties of Ni0.5Co0.5FeCrO4 sintered at 5000C, 6000C, 7000C and 8000C for 6h.
