Electrical and magnetic properties of Mn-Ni-Zn ferrites processed by citrate precursor method
MnxNi0.5 _ xZn0.5Fe2O4, (x = 0.05, 0.1, 0.2, 0.3, 0.4) ferrites synthesized by the citrate precursor method are investigated in the present work. Compositional variation of AC resistivity is studied and values up to 10 times greater than those for samples prepared by the conventional ceramic method are observed. It is found that resistivity decreases with increase in Mn concentration except for...
متن کاملEnhancement of the Magnetic Properties for Co-Mn-Zn Ferrites
Aluminum substituted cobalt manganese zinc ferrite nanoparticles Co0.425Mn0.425Zn0.150AlxFe2-xO4 (from x= 0.0 to 0.15 with step 0.025) have been synthesized by chemical co-precipitation route. X-ray diffraction (XRD) and infrared spectroscopy (FTIR) revealed that the obtained powders have a single phase of cubic spinel structure. The crystallite sizes calculated from XRD data have been confirme...
متن کاملStructure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method
Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...
متن کاملPreparation and investigation of magnetic properties of Manganese Cadmium ferrite nanoparticles by Sol-gel method
In the present investigation, manganese ferrite nanoparticles substituted by cadmium with Mn1-xCdxFe2O4 composition and substituted amount x=(0, 0.1, 0.3, 0.5) were prepared by Sol-gel method. Pattern analysis of X-ray diffraction (XRD) confirmed ferrite single phase structure in all samples. The average crystal size was estimated from 17 to 22 nm. The chemical bonds and ferrite formation phase...
متن کاملSTRUCTURAL AND MAGNETIC PROPERTIES OF Co-Nd SUBSTITUTED ZnFe2O4 FERRITES SYNTHESIZED BY CO-PRECIPITATION TECHNIQUE
A series of Zn1-xCoxNdyFe2-yO4 spinel ferrites (x=0,0-0.5, y=0.00-0.10) was synthesized using the co-precipitation method sintered at 1000 o C. Synthesized Ferrites were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometery (VSM). The diffraction patterns show the formation of the spinel phase along with some traces of second phase Nd2O3...
