In this work, we investigated synthesis, magnetic properties of silica coated metal ferrite, (CoFe2O4)/SiO2 and Manganese doped cobalt ferrite nanoparticles (MnxCo1-xFe2O4 with x= 0.02, 0.04 and 0.06)/SiO2 for possible biomedical application. All the ferrites nanoparticles were prepared by co-precipitation method using FeCl3.6H2O, CoCl2.6H2O and MnCl2.2H2O as precursors, and were silica coated ...

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...

Nanocomposite zinc ferrites were synthesized using glycine-nitrates by sol–gel auto-combustion technique. The influence of calcination temperatures varying from 400 to 900°C on structural and magnetic properties of spinel ZnFe2O4 powders have been investigated. The characterization measurements including X-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetomet...

Abstract Metal ferrites have outstanding electrochemical characteristics owing to the numerous oxidation states of metal ions, making them promising materials for addressing both sustainable energy conversion and storage growing environmental issues. Therefore, three nanocrystallites transition ferrites, CoFe 2 O 4 , CuFe Co/CuFe were synthesized using citrate precursors used as electrode super...

Due to recent advances in communication systems, dielectric and magnetic ceramics (ferrites) are attractive for use devices. Spinel-type ferrites were the first material utilized microwave devices; however, yttrium iron garnet (YIG) has low losses is exploited many applications. Owing its high Faraday rotation, YIG films magneto-optical This study intends examine research trends scientific prog...
