Ferrites Obtained by Sol–Gel Method

Abstract

Ferrites are ferrimagnetic materials, a broad class of magnetic oxides with its remarkable structural, electrical, and magnetic properties making them suitable for a variety of applications. These properties strongly depend upon the method of preparation. Sol-gel method is having countless advantages over other methods to obtain the ferrite with desired nanoarchitecture. In this chapter, the effects of

Effect of the neodymium doping on the magnetic and structural properties of the Sr-hexaferrite obtained by the Pechini method

“…The Pechini sol-gel method has great advantages over other methods to obtain materials with the desired shape and depending on the experimental parameters, obtain up to nanometric size. In this sense, multiple factors intervene in obtaining the final product, such as the relationship between the precursor salts, reaction of temperature, pH, and sintering time/temperature [12].…”

A study on microstructure and magnetic properties of nanostructured CoxNi1-xMn0.5Fe1.5O4(x=0,0.25,0.5,0.75,1) spinel ferrites

“…An organic solvent and surfactant in a reaction controls the size and shape-morphology of yielded nanostructured ferrite powder. A complete removal of organic contents from interacting surfaces of nanostructured ferrites is extremely important for optimum display of magnetic parameters like M s and H c [7,8].…”

Synthesis, Microstructural and Electromagnetic Characteristics of Cobalt-Zinc Ferrite

“…Now, there are various methods for obtaining both nano-sized and micro-sized ferrite powders using ceramic technologies and from salt solutions [5][6][7]. The production method significantly affects the shape and size of the particles, which determines the microstructural and electromagnetic properties of the material [8][9][10]. For example, one of the most widespread methods of obtaining ferrite powder is ceramic synthesis [11][12][13][14].…”
