Structural, magnetic and electrical properties of Al3+ substituted Ni–Zn ferrite nanoparticles

“…Various physical properties of nanocrystalline ferrites are highly influenced by distribution of cations among the sub lattices, nature of grain (shape, size, and orientation), grain boundaries, voids, in homogeneities, surface layers, contacts, etc. [1][2][3]. The information about the associated physical parameters of the microstructural components is important; since, the overall property of the materials is determined by these components.…”

“…Progresses in the use and development of new ferrites have been rapid as compared to other areas of research [4][5][6][7][8][9]. One important characteristic of ferrites is their high values of resistivity and low eddy current losses [10][11][12][13], which make them ideal for high frequency applications. For microwave applications, the dielectric properties such as dielectric constant and dielectric loss are very important as the dielectric constant affects the thickness of microwave absorbing layer and the dielectric loss factor (tan ı) of a material determines dissipation of the electrical energy.…”

Enhancement of electrical properties due to Cr3+ substitution in Co-ferrite nanoparticles synthesized by two chemical techniques

“…It is also noticed that intensity of the absorption band u 2 decreases with increasing Cr 3 þ concentration. It is known that the intensity ratio is a function of the change of dipole moment with the internuclear distance (dm/dr) [21]. This value represents the contribution of the ionic bond Fe-O in the lattice.…”
