Temperature dependence of spin resonance in cobalt substituted NiZnCu ferrites
Cobalt substitutions were investigated in Ni0.4Zn0.4Cu0.2Fe2O4 ferrites, initial complex permeability was then measured from 1 MHz to 1 GHz. It appears that cobalt substitution led to a decrease of the permeability and an increase of the μs×fr factor. As well, it gave to the permeability spectrum a sharp resonance character. We also observed a spin reorientation occuring at a temperature depend...
متن کاملSpinel ferrites as efficient magnetically reusable nanocatalysts in the solvent-free synthesis of substituted trisphenols
A series of copper and cobalt substituted nanospinel ferrites have been synthesized by the hydrothermal method. These compounds were characterized by FT-IR, XRD, EDX, SEM and VSM techniques. All of the synthesized nanospinel ferrites were found to be highly efficient and magnetically recoverable in the solvent-free synthesis of substituted 2,6-(2-hydroxybenzyl)-phenols (trisphenols). A wide ran...

متن کاملFerromagnetic Properties of Zn substituted Spinel Ferrites for High Frequency Applications
This review focuses on two systems, nanocrystalline Zn substituted Co1-xZnxFe2O4 (0≤x≥1) and Ni0.4Zn0.2Mn0.4Fe2O4, were synthesized using microwave hydrothermal and auto-combustion method respectively. The synthesized powders were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), thermo-gravimetricdifferential thermal analysis (TG-DTA) and FTIR. The average parti...
متن کاملZn2– xSn1– xIn2 xO4 –d : An Indium-Substituted Spinel with Transparent Conducting Properties
Transparent conducting oxides (TCO’s) have widespread uses as electrodes in solar cells and liquid crystal displays and as heat-reflecting window coatings. The commercial TCO of choice is ITO (tin-doped indium oxide). ITO has a typical conductivity of 1!5]103 S/cm and a transparency 85—90% in thin films (1). In addition to ITO, which has been reviewed (2), a number of promising TCO’s consisting...
