“…This difference is a result of the porous structure of the growing sample during sintering or production (Rafiq et al, 2015). To determine the physical and electrical properties of the ferrites, it is important to examine the morphology and grain shapes of the samples (Şaşmaz Kuru et al, 2019).

“…Imaginary part of dielectric constant, known as dielectric loss, consists of three parts, namely conduction losses, dipole losses and vibration losses (Jaidka et al, 2018;Polat et al, 2020). It is possible to explain the occurrence of dielectric loss in materials, the reduction of the charge storage capability by the independent movement of electric polarization with the changing electric field (Kuru et al, 2019).

In this study, structural, morphological, dielectric and AC conductivity properties of CoMgLa ferrite samples (Co0.5Mg0.5LaxFe2-xO4) were investigated according to the change of x (x=0, 0.1, 0.2, 0.3, 0.4 and 0.5). Samples were synthesized by co-precipitation method. The structural properties were examined using XRD and results show that the prepared sample crystallizes in the cubic spinel structure. Crystallite sizes are changing between 24.92 to 9.80 nm. Morphological and elemental properties were analyzed by SEM and EDX. Dielectric properties were investigated by impedance spectroscopy. The samples showed normal dielectric properties consistent with the Maxwell-Wagner model due to interfacial polarization. When the impedance characteristics were examined, it was found that the relaxation process was compatible with the Cole-Cole model. The results of the modulus show that grains contribute to the relaxation process as well as grain boundaries. AC conductivity exhibited semiconductor behavior. The constant behavior of conductivity at low frequencies is a sign that the examined samples may be suitable for many applications.

“…Such type of ferrite is suitable for microwave absorbing applications. M. Kuru et al [22] synthesized CaxNi0.75-xZn0.25Fe2O4 (x=0, 0.25, 0.5 and 0.75) by adopting chemical coprecipitation synthesis process. In XRD investigation, lattice parameter varied from 8.334 Å to 8.538 Å and crystal structures were cubic spinel for all samples.…”

Nanotechnology, when this word comes in mind, it gives deep thought of new development in communication, medical science, intelligent transport system and many more. Ferrites nanoparticles have great significance owing to their amazing chemical and physical properties. In modern era we are developing materials for microwave applications and communication devices. Before the discovery of semiconductor memory chips, ferrites were the major form for electronic memory used in computers. Scientist have been studying and working with nanoparticles in magnetically guided drug delivery. The reactivity of material increases by the use of nanoparticles of that material. The dielectric characteristics of ferrites lean on diverse factors for instance methods of preparations and chemical composition. In various studies it has been found that their conductivity has dependence on temperature, composition and frequency. Among the various kinds of ferrites, Ni–Zn ferrites are viewed as the most adaptable ferrites as a result of their novel characteristics for applications at high frequency. The Ni-Zn ferrites are exploited as core materials in a variety of EM devices as well as have broad range of industrial applications e.g. inductors, microwave devices, power supplies, high and low frequency transformer cores, electromagnetic interference (EMI) suppressions and antenna rods. These broad ranges of applications are owing to their high resistivity, low eddy currents, high saturation magnetization, chemical stability and high Curie temperature. In view of this, the present chapter deals with the research progress on nickel-zinc ferrites in the bulk as well as nano size.
