“…The value of dc resistivity for the present ferrites is around ∼10 13 cm, meeting the requirement of MLCIs [12]. The high resistivity observed in the present samples may be due to the substitution of nickel by copper that resists the oxidation of Ni +2 to Ni +3 .…”

Nanocrystalline Ni 0.5 Cu 0.3 Zn 0.2 Fe 2 O 4 (NCZFO) powder was fabricated by a modified sol-gel method and then the compacted powder of NCZFO was sintered at 950, 1000, and 1100 • C for 6 h. The dielectric and electrical properties of sintered samples were investigated as functions of frequency and temperature. All of the NCZFO samples exhibit the high dielectric response behavior and show the Debye-like relaxation, which is attributed to the Maxwell-Wagner polarization and thermally activated mechanisms. The impedance spectroscopy analysis reveals that the NCZFO ceramics are electrically heterogeneous. The sintering temperature has significant influence on the dielectric dispersion behavior of the NCZFO samples, which should be mainly attributed to the large variation of the grain conduction activation energies.

“…Nickel copper zinc ferrites with their ease of preparation and versatility for use in wide variety applications are commercially very attractive. Nickel copper zinc ferrites with high permeability and a high Curie temperature have been widely studied for practical and microwave applications [3,4]. Ferrite chip inductors are one of the important components for the latest electronics products such as cellular phones, video cameras, notebook computers, hard and floppy drives [5], etc.…”

Nickel copper zinc ferrites with composition of Ni0.2Cu0.2Zn0.6Fe2-xHoxO4 (x=0.0 to 0.1 in steps of 0.02) synthesized by the sol-gel autocombustion method. Sintering temperature of precursors determined using TGA-DTA. XRD patterns indicate that all samples have single phase cubic spinel structure. The IR spectra show two major absorption bands. The microstructures of the prepared samples were studied by SEM and TEM. Elastic moduli and Debye temperature were determined using IR data and XRD data of spinel ferrite samples. The values of Debye temperature, Young's modulus (E), bulk modulus (K) and modulus of rigidity (G) and stiffness constant increased with holmium substitution.
