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.

The only available calculations concerning propagation in ferrite slab loaded waveguides are those of Lax, Button and Roth which are limited to transverse electric type modes. Due to its incompleteness the theory leads to certain anomalies which have been the subject of considerable discussion in recent years. It is the purpose of the work ... to solve the anomalies dealing with one-way transmission and with the field displacement isolator. This is done largely through experiments which indicate the extent to which the theory is able to predict the actual mode configurations.
