“…The value of the lattice parameter for each composition has been calculated using the values of d-spacing. In the case of ZnFe,O,, the value of the lattice parameter obtained in the present investigation is 0.8441 nm, which is in agreement with that of 0.8440 nm reported by Josyulu and Sobhanadri [4] and Pran Kishan et al [5]. No data are available in the literature to compare the values of other Li-Zn ferrites.…”

Mixed Li-Zn ferrites are prepared by the well-known double sintering ceramic technique. From the X-ray diffraction studies lattice parameters are calculated and their variation with composition is explained on the basis of the tetrahedral ionic radius. The bulk density of the specimens are determined by the hydrostatic method. The ultrasonic compressional (6) and shear (V,) velocities of mixed Li-Zn ferrites are measured at room temperature using the ultrasonic pulse transmission technique. The elastic moduli of the specimens are computed and corrected to zero porosity. The variation of elastic moduli with composition is interpreted in terms of binding forces between the atoms. 28 physica (a) 136/2

“…It can be seen from the table that the bulk density increases and the porosity decreases progressively with addition of zinc to nickel ferrite. Zinc ferrite having the least porosity, this conforms the observation that the addition of zinc to nickel ferrite results the densification of the material [27]. The variation of bulk density with zinc content for mixed Ni-Zn ferrite is shown in the Figure 5.…”

Ni-Zn ferrite with a nominal composition of Ni 1-X Zn X Fe 2 O 4 (X = 0, 0.2, 0.6, 0.8, 0.9 and 1.0) ferrite powders have been successfully prepared at a very low temperature (180˚C) by a novel auto combustion process using citric acid as a coordinating agent. Phase purity of the solid solutions has been confirmed by X-ray diffraction. Morphological, elemental composition characterizations of the prepared samples were performed by high resolution scanning electron microscopy and energy dispersive spectroscopy (EDS). Magnetic properties of all samples are obtained by using VSM (Vibrating Sample Magnetometer) in the range of 10 K oe. The saturation magnetization values of the samples are carried out from the B-H loop. The effect of composition on saturation magnetization and magnetic moment are studied in this paper. The results showed that Saturation magnetization and magnetic moment values increases gradually as Zn 2+ composition increases, it reaches maximum value 70.28 emu/gm for (X = 0.6) and decreases further with increasing Zn 2+ composition.

“…It is minimum in the case of lithium ferrite sintered at 950 "C. The decrease of the dielectric constant with increasing frequency as observed in the case of lithium ferrite sintered at different temperatures is the normal dielectric behaviour of spinel ferrites. This normal dielectric behaviour was also observed by Pran Kishan et al [9] in the case of lithium-zinc ferrites. Reddy and Reddy [lo] observed similar normal dielectric behaviour in the case of Li-Ti ferrites.…”
