This book was released on 2012 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is great deal of interest in transparent Dilute Magnetic Semiconductors (DMS) due to their potential applications in spintronics. Nanomaterials of transition-metal doped ZnO DMS are considered as ideal systems for carrying out research in the field of spintronics as they can successully combine magnetism and electronics in a single material. In this thesis, ZnO and Co-doped ZnO nanorods have been synthesized by hydrothermal method using aqueous solutions of Zn (NO3)2 .6H2), Co (C2H3OO)2.4H2O, and NH4OH as hydrolytic catalyst. Pure as well as transition element doped ZnO nanomaterials with different sizes and shapes have been synthesized through changing process parameters such as molarity of the precursors, pH of the final mixture, growth and annealing temperature and time during the hydrothermal process. Structural, magnetic, and optical properties are studied using available state-of-the-art techniques such as X-ray diffration (XRD), field emission scanning electron microscopy (FESEM), superconducting quantum interference device (SQUID) magnetometer and ultraviolet-visible spectroscopy. XRD and SEM studies have revealed nanorods with hexagonal Wurtzite structure with length in the range of 200 to 5000 nm, and cross section in the range of 30 to 500 nm. Magnetization data suggest an existence of complex magnetic structure in the (10%, 5%, 2%) Co-doped ZnO nanomaterials. Further investigation is required to better understand the complex nature of magnetic properties in transition metal doped DMS. Understanding of DMS is critical for the future spin-electronics.

Book Synopsis Synthesis and Characterization of Cobalt Carbide Based Nanomaterials by : Zachary John Huba
Download or read book Synthesis and Characterization of Cobalt Carbide Based Nanomaterials written by Zachary John Huba and published by . This book was released on 2014 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permanent magnets are used heavily for multiple applications in industry and current electronic technologies. However, the current permanent landscape is muddled by high cost of materials and insufficient magnetic or thermal properties. The primary focus of this dissertation work is the synthesis and optimization of a new permanent magnetic material, in the form of cobalt carbide nanomaterials. The optimization revolved around controlling the crystal phase and particle shape of synthesized cobalt carbide particles; these parameters have significant impact on the observed magnetic properties of magnetic nanoparticles. Co3C was identified to be the preferred crystal phase, leading to better magnetic properties. Cobalt Fumarate was found to be the ideal precursor to synthesize anisotropic Co3C particles and enhance magnetic properties of the synthesized cobalt carbide particles. Lastly, an ethanol based reduction system was employed to develop the greener synthesis of Co and Ni magnetic particles.
