Book Description
Self Organization Magnetic Arrays (SOMA) made from self-assembled magnetic nanoparticles produced by solution phase chemical approaches have been considered as the most promising candidate for ultra-high density magnetic recording media with potential areal density beyond 1Tb/in2. This thesis is focused on the fabrication of CoPt and FePt-type nanoparticles by chemical synthesis for the application in magnetic recording media. The work in this thesis consists of three parts. Synthesis and characterization of CoPt and FePt nanoparticles were investigated.

Book Description
The structural, microstructural, and magnetic properties of Mn1-xBixFe2O4 (where x = 0.0, 0.05, 0.1, 0.15, and 0.2) nanoparticles prepared by solution combustion method were investigated. Rietveld-refined X-ray diffraction patterns confirm the single-phase formation with space group Fd3m having spinel cubic structure. The porous nature of the samples was confirmed by scanning electron microscopy (SEM). Composition values of the theoretical stoichiometry and energy-dispersive spectroscopy (EDS) composition values are well matched for all samples. The dielectric parameters such as real part of dielectric constant, imaginary part of dielectric constant, and dielectric loss tangent decrease with the increase in frequency. The AC conductivity increases with increase in the Bi3+ concentration. The real part of complex impedance decreases with the increase in frequency. Cole-Cole plots reveal that one semicircle was obtained for each of the samples. The real and imaginary parts of electric modulus vary with frequency. The magnetic hysteresis curves of all samples reveal the soft magnetic material nature. We observed S esteems began uniquely from the higher superparamagnetic, we would have watched the monotonic decrease in S with increase in Bi3+ concentration. Furthermore, the magnetic parameters were estimated.
