ABSTRACT. Nickel zinc nano particles Ni x Zn 1-x Fe 2 O 4 (where x= 0.2, 0.4, 0.5, 0.6 and 0.8) by Chemical Co-Precipitation method. The samples were characterised by X-ray diffraction (XRD), TEM, VSM. The powders of XRD patterns confirm a single spinel crystalline phase with cubic structure formation with no indication of any other secondary or unidentified phase. The lattice parameter changed from 8.336 Å to 8.382 Å. The average particle size ranged 20 to 80 nm was observed by TEM.

“…This may suggest the lower probability of the ions of the samples under investigation existing in different valence states, which reduces the possibility of electron hopping and hence of polarization among the grains, resulting in the low values of the dielectric constant as well as the dielectric loss. This low dielectric constant behavior is quite useful for the high frequency application by reducing the eddy current effect [33]. Fig.…”

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.
