Synthesis of Ni-Zn And Ni-Zn-Cu Ferrite Via Sol-Gel Route and Solid State Reaction

A ferrite is an important class of magnetic materials. At present the major material types for application of spinel soft ferrite are nickel-zinc and manganesezinc ferrites. A majority of these ferrites are synthesised by the classical method which is the conventi onal ceramic process known as so...
