STRUCTURAL 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...

Metal oxide nanomaterials are important and excellent materials, because of its special properties like chemical stability, high photo catalytic activity, high electric permittivity, non-toxic nature. So it is used in various applications like optical, electrical, electronic, antiseptic, antibacterial, environmental, semi conductors and catalytic devices. Present work focused on to synthesis of...
متن کاملValidity of the Néel-Arrhenius model for highly anisotropic CoxFe3-xO4 nanoparticles
We report a systematic study on the structural and magnetic properties of CoxFe3-xO4 magnetic nanoparticles with sizes between 5 to 25 nm, prepared by thermal decomposition of Fe(acac)3 and Co(acac)2. The large magneto-crystalline anisotropy of the synthesized particles resulted in high blocking temperatures (42K< TB< 345K for 5 < d < 13 nm) and large coercive fields (HC ≈ 1600 kA/m for T = 5 K...
متن کاملSynthesis and characterization of SnO2 nanoparticles by Co-Precipitation method
Tin oxide (SnO2)nanoparticles were synthesized by co-precipitation method and the synthesized nanoparticles were annealed at different temperatures for characterization. The powders were investigated with X-ray diffraction, scanning electron microscopy and optical spectroscopy. The structural characterization was carried out by X-ray diffraction which confirms the crystalline nature ...
