The main purpose of this research work is to develop the single domain magnetic particles of M-type Barium hexa-ferrite having composition of BaFe12O19 using oxide precursors using conventional powder metallurgy technique. The phase formation and magnetic performance of the powders and magnets will be optimized by adjusting calcination and sintering temperatures. The synthesis of M-Type Barium hexa-ferrite carried out in two sections. A series of four samples have been prepared by initial wet mixed powders calcined at different temperatures i.e. 750, 850, 950 and 1050oC. On the basis of structural analysis the sample calcined at 950oC has been selected and further divided into four parts to sintered them at 1100, 1150, 1200 and 1250oC. These are characterized through Differential Scanning calorimetric (DSC), X-ray Diffractometer (XRD), Diamond Structure visualization software, Fourier transform infrared (FTIR), Scanning electron microscope (SEM) and DC-Magnetometer. The structural measurements depict the confirmation of M-Type Barium Hexa-ferrite structure. SEM micrographs show the hexagonal shaped like grains. The coercivity of the sample sintered at 1250oC has a minimum value.

With progressions in technological advancements, new materials are being developed to meet industrial requirements. One such Nickel based super alloy is Inconel 625. Inconel 625 exhibits extraordinary mechanical properties along with chemical stability at high temperature. Due to extraordinary mechanical, physical and chemical properties, Inconel 625 is exceptionally hard to machine/finish. In this book, magnetic abrasive finishing process has been proposed to finish flat Inconel 625 surfaces. Three different parameters processing time, pole rotational speed and weight percentage of abrasives and their range has been selected. Design expert software has been used to plan experiments. Seventeen experiments were conducted as per experimental plan. The effect of process parameters on output characteristics (Percentage improvement in surface finish and Material removed) has been analyzed. Microscopic analysis and SEM analysis of few work pieces has been also provided to analyze the effect of process parameters.

Magnetic Nanowires

Magnetic nanostructures have attracted increasing attention because of their potential applications in high-density data storage and in sensor technology. An understanding of the fundamental physical properties of these nanostructures is of interest in the study of atomic structures and micromagnetism. This book presents a study on the growth of nickel nanowires in commercially available templates. Electrodeposition was used through the pores of a template to produce nanowire matrices. Dependence of the nanowire growth rate, quality of deposit, growth uniformity, crystal orientations and other physical properties of the nanowire network were studied using various process parameters. Structural properties of the nanowire were characterised using AFM, SEM, EDX and TEM. Magnetic properties of the nanowires were studied using a VSM and MFM. Using OOMMF software magnetic behaviour of the nanowires was simulated and compared with the experimental coercivity values and magnetisation behaviour. The target audience of this book is the postgraduate students and the researchers who would like to study the fabrication and characterisation of magnetic nanowires.
