Structural and Electrical Characterization of Ni-Zn Ferrites
The effect of Zn substitution on the DC electrical resistivity, AC electrical conductivity and microstructure of V2O5 doped Zn(1-x)NixFe2O4 with x=0.0, 0.1, 0.2, 0.3, 0.4 (5 samples) were prepared by conventional ceramic technique has been investigated. The structural characterization of nickel-zinc ferrites were done by X-ray diffraction technique. Micro-structural and morphological studies we...
متن کاملElastic behaviour of Sn doped Ni-Zn ferrites
The polycrystalline Sn added Ni-Zn ferrites were prepared using the conventional sintering method. The monophasic nature of the samples was characterized using X-rays. The elastic behavior has been measured in the temperature range 80-410oC using the composite oscillator method. The values of Young’s and shear modulus are corrected to theoretical density using the method of Mackenzie method. Th...
متن کاملInterfacial Dielectric Losses in Co-Doped Ni-Zn Ferrites
The temperature and fresuency dependence of tg8 and E' for Nk ~Ztb ferrites was studied in the 10'lo6 Hz frequency range and 20-200°C temperrhrre tange. The experimental curves exhibit aspects very dependent of composition. To verify Ulat interfacial losses, expected to appear in this type of system are compatible with the experimental results a calculation of the dielectric permittivity and di...
متن کاملMicrostructure and grain growth of nanosized materials
An anomalous dependence of the lattice parameter on the crystallite size of nanocrystalline ball-milled powders of metals was observed: lattice contraction followed by lattice expansion with decreasing crystallite size. These data were determined by application of detailed Xray diffraction measurements. To this end, the lattice parameters of all the metals were accurately determined by correcti...
متن کاملEnhancement of Néel temperature and electrical resistivity of Mn–Ni–Zn ferrites by Gd3+ substitution
Structural, magnetic, and dielectric properties of various Mn0.5Ni0.1Zn0.4Fe2−xGdxO4 sintered at 1200 ◦C were investigated thoroughly. The samples were synthesized by standard solid state reaction technique. The crystal structure was characterized by X-ray diffraction (XRD), which has confirmed the formation of single phase spinel structure. Bulk density, average grain size and initial permeabi...
