“…16(a)). A similar anomaly was found by Mohamed et al 73 for a nanocomposite PANI-Ni 0.5 Zn 0.5 Fe 1.5 Cr 0.5 O 4 around 333 K and by Tan et al 74 at 305 K. This peak may be attributed to local polarization 75 and its wide dispersion indicates the diffuse character of phase transition that the material undergoes. 76 With increasing frequency, the dielectric maxima shi to higher temperatures.…”

“…The gel was obtained by stirring all the ingredients at room temperature for about 1 day, followed by drying at 400 • C for 1 h and cooled to room temperature [10,11]. The samples were characterized by X-ray diffraction (XRD) using a Philips diffractometer (X'Pert MPD) with Cu Kα radiation.…”

Nanocrystalline Ni 1−x Zn x Fe 1.5 Cr 0.5 O 4 (0 ≤ x ≤ 0.5) ferrite was prepared using a citrate method. The influence of Zn 2+ ion substitution on structure, magnetic, and electric properties of the Ni 1−x Zn x Fe 1.5 Cr 0.5 O 4 ferrite has been investigated. The X-ray diffraction results confirmed the formation of a single phase with a spinel cubic structure for Ni 1−x Zn x Fe 1.5 Cr 0.5 O 4 samples. The magnetization was found to be influenced by the surface spin canting angles, the porosity percentage, and the cation distributions. The variation of dielectric constant with temperature indicated that the investigated materials can be recommended to be used as good insulating ceramic materials at room temperature and as a semiconductor at higher temperatures.

Chromium substituted Mn nanospinel ferrites having the formula MnCr x Fe 2-x O 4 (0.0 B x B 1.0) have been synthesized using the microwave-assisted combustion synthesis. The composition, structural, spectroscopic features of the products were studied by X-ray powder diffractometry (XRD), Fourier transform infrared spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy. XRD investigations indicated the formation of single-phased cubic spinel structure for all products. Lattice parameters of the products represented the continuous decrease with increasing the substitution of Cr 3? . The saturation magnetization of undoped sample appeared to be highest and as Cr 3? concentration increases magnetization of the samples decreases. There is one reflection loss minimum in all doped samples at around 13 GHz with magnitude of -12 dB mechanism of which is explained by quarter wave cancellation model.
