“…Although the order of increase of ionic size is like Ni, Sm and Zn the values of magnetic moment Table 2 and force constant show a deviation for Ni substituted Zn ferrite. The deviations of ionic moment verses magnetic moment and bond length versus force constant of these ferrites are accounted for by a substantial role of crystal field effect [15] initiated by Zn ions. …”

Nano-particles of polycrystalline Zn Fe 2 O 4 are prepared using sol-gel method with Ni, and Sm. They are obtained as dried gel after the successful chemical reaction of their respective metal nitrate solutions in the midst of citric acid as catalyst. Synthesis of materials is confirmed using XRD from the report of single phase polycrystalline ferrite material. The magnetic properties of Zn-ferrite ceramics Zn 1-x-y Ni y Sm x Fe 2 O 4 , (where x = 0.01, 0.012, 0.014, 0.016, y=0.001) were synthesized by sol gel auto combustion method. The structure and composition of Sm doped Zn-ferrite ceramics were analyzed and the nano size was confirmed by the SEM monographs. The VSM studies confirm the magnetic behaviour by analyzing the change in magnetic saturation and coercivity of these nano materials.

“…Hence the knowledge of the frequency dependence of the initial permeability and loss is necessary. Cu-ferrite and Cucontaining ferrites form an interesting group of ferrites because of their typical electrical and magnetic properties and change in crystal structure on thermal treatment [2]. Znsubstituted Cu-ferrite have been commercially used for many years as high-frequency devices such as radio frequency coil, transformer cores, rod antenna etc.…”

Cu-Zn ferrites of composition Cu 1-x Zn x Fe 2 O 4 were prepared by double sintering ceramic technique at 950 0 C and 1050 0 C for 3 hours and 2 hours, respectively. Structural and magnetic properties of the Cu-Zn ferrites were investigated by using X-ray diffraction, microstructure study and complex permeability behaviour. X-ray analysis indicated the formation of single-phase cubic spinel structure for all samples. The lattice parameter was found to increase with increasing Zn content obeying Vegard's law. The X-ray and bulk densities of the Cu-Zn ferrite significantly decreased whereas porosity increased with increasing Zn concentration. Micrographs exhibited decrease in grain size with increasing concentrations. The real part μ'of initial permeability remained constant up to certain lower range of frequency after which it decreased to lower value of permeability. μ' increased with increasing Zn contents up to x = 0.5, after that it decreased with higher Zn content but was also found to increase with sintering temperature. The possible reasons responsible for change in structural, microstructural and complex permeability with increasing of nonmagnetic Zn 2+ ion are ascertained.

“…Thus, the magnetic and electric properties of nickel ferrite have been researched and improved [7]. Cucontaining ferrites form an interesting group of ferrites because of their typical electrical and magnetic properties and change in crystal structure on thermal treatment [8]. Cu-Cd nano-ferrites are low cost materials and have important magnetic and electrical properties for technological applications.…”

A series of copper substituted cadmium nano ferrites with the compositional formula Cu 1-x Cd x O 4 (where x=0.1, 0.3. 0.5 and 0.7) were prepared by the Citrate gel auto combustion technique and sintered at 873 K for 4 hr. The X-ray difractrograms (XRD) clearly exhibited the existence of single phase cubic spinel structure. The crystallite size was found in the range of 10-42nm. The values of lattice parameter were calculated by using d spacing. The calculated values of lattice parameter and X-ray density were explained on the basis of composition.
