Magnetic, dielectric and complex impedance spectroscopic studies of nanocrystalline Cr substituted Li-ferrite

Synthesis and characterization of nanocrystalline Ti-substituted Zn ferrite

“…It is a simple process, which saves time and energy consumption over the traditional methods and requires only low sintering temperature. This method is employed to obtain ferrites having improved powder characteristics, more homogeneity and narrow particle size distribution [8,9]. To our knowledge, there are no reports on the synthesis and structural property study of the nanocrystalline titanium substituted zinc ferrite, prepared by sol-gel autocombustion method.…”

Electrical characteristics of Li(Ni7/10Fe3/10)VO4 ceramics

“…and chemical properties. The electronic nature of these oxides gives information about electrical behavior and it may be related to structural/microstructural properties [16][17][18]. Complex impedance spectroscopy technique is used to study the electrical properties of such type of materials [18,19].…”

Structure and electrical conduction behavior of LiZnVO4 ceramic prepared by solution-based chemical route

“…Furthermore, the physical properties of these oxides are controlled by the preparation conditions, chemical composition, sintering temperature and time, type and amount of substitutions. Electrical measurements have been considered as an important tool for studying the electrical transport properties of these materials [6,[10][11][12][13][14][15]. The a.c. impedance spectroscopy is a very convenient and powerful experimental technique for electrical measurements.…”

“…This technique enables us to correlate the electrical properties of a material with its microstructure, and also helps to analyze and separate the contributions from various components (i.e., grains, grain boundary, interfaces, etc.) of polycrystalline materials in the wide frequency range [10][11][12][13][14][15]. From the measured data, the complex impedance function is computed as Z * = Z − jZ , where Z and Z are the real and imaginary parts of Z * respectively, and j = (−1) 1/2 .…”

“…From the measured data, the complex impedance function is computed as Z * = Z − jZ , where Z and Z are the real and imaginary parts of Z * respectively, and j = (−1) 1/2 . The complex impedance diagrams helps to build up an equivalent circuit model for the conduction process of charged carriers [10][11][12][13][14][15]. Many researchers have used a.c. impedance spectroscopy technique to characterize the electrical transport properties of lithium-containing transition metal oxides [6,[16][17][18][19][20][21][22].…”
