Frequency dependent dielectric behaviour of cadmium and chromium co-substituted nickel ferrite

The frequency dependent dielectric properties of Ni1−xCdxCrxFe2−xO4 (x = 0.0, 0.3, 0.5, 0.7 and 1.0) spinel ferrite system are studied by measuring dielectric constant (ε′), dielectric loss (D) and conductivity (σa.c) at 300 K in the frequency range 100 Hz-2 MHz. The highest value of σa.c and ε′ is observed for x = 0.3 composition. The values ε′ and σa.c decrease with increase in frequency for ...

Synthesis and characterization of Nickel Copper Ferrite

Nano size nickel copper ferrite powders (NiCuFe2O4) have been prepared by a prepared by Co precipitation method. The resulting powders were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The result showed nanosize nickel copper ferrite(35.65nm). The powders showed extensive XRD line broadening and sizes of crystals observed from the XRD line broadening was35.65 nm,...

Study Concentrations Changes of Lead, Chromium, Nickel, Cadmium, Zinc and Copper in Beshar River of Kohgiluyeh and Boyerahmad Province, Iran

Due to the lack of water quality of resourses in country, exact review of available water resources quality, especially in terms of heavy elements (heavy metals) has a particular importance. Due to industrial towns 1 and 2 of Yasuj city and also Yasuj wastewater treatment, surveying environmental harmful effects of heavy metals on this river is very important. To investigate the changes of heav...

Thermal Evolution of Cation Distribution/Crystallite Size and Their Correlation with the Magnetic State of Yb-Substituted Zinc Ferrite Nanoparticles

Evolution of the structural and magnetic properties of ZnFe1.95Yb0.05O4 nanoparticles, prepared via a high-energy ball milling route and exposed to further thermal annealing/heating, was assessed in detail and correlation of these properties explored. While as-prepared spinel nanoparticles possess a high degree of inversion, heating of the sample to ∼500 °C is found to rapidly alter the cation ...
