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.

The book includes the remarkable information of use of nano-crystalline Mg-Cd and Nd3+substituted Mg-Cd ferrites as substrates for microstrip patch antenna. The details of ferrites synthesis by oxalate co-precipitation method under microwave sintering were well explained. Overall detailed explanation of results obtained from synthesis, characterization using XRD, FE-SEM, EDAX and FT-IR technique and magnetic properties of ferrite materials was described. The explanation of effect of microwave sintering of structural properties of ferrite was given precisely. The details measurements of permittivity, dielectric loss tangent, permeability, magnetic loss tangent, reflection loss of ferrites were also included. The design of microstrip patch antennas on synthesized ferrite using these electromagnetic parameters with help of Ansoft Designer SV2 software was described. The procedure of fabrication of substrates of ferrite, printing of silver patches on ferrite substrates and connection of SMA connectors at proper locations was given in this book. Finally this book explains information about analysis by simulation and measurements of antenna parameters on vector network analyzer.
