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,...
متن کاملMicrowave-assisted synthesis, microstructure, and physical properties of rare-earth chromites.
The full rare-earth (RE) chromites series (RE)CrO(3) with an orthorhombic distorted (Pnma) perovskite structure and the isostructural compound YCrO(3) can be synthesized through a simple microwave-assisted technique, yielding high-quality materials. Magnetization measurements evidence that the Néel temperature for antiferromagnetic Cr(3+)-Cr(3+) ordering strongly depends on the RE(3+) ionic rad...
متن کاملSynthesis and Structural Studies of Nickel Doped Cobalt Ferrite Thin Films
The growth and structural study of Nickel doped Cobalt ferrite thin films on glass substrate using spray pyrolysis technique have been done. The structural studies confirmed the growth of polycrystalline film having cubic structure with Fd3m space group. The x ray density was found to increase with Ni concentration, where as the reduction, in crystalline size, was found in XRD m...
متن کاملSynthesis and characterization of non-stoichiometric nickel-copper manganites
Non-stoichiometric nickel–copper manganites Ni Cu Mn h O were synthesized by thermal decomposition of x y 32x2y 3d / 4 41d mixed Ni Cu Mn C O , nH O oxalates in air at low temperature (623–673 K). X-ray diffraction showed that, x / 3 y / 3 (32x2y) / 3 2 4 2 for a nickel content x $ 0.1, the oxalates precipitated presented a mixed crystal structure up to a limit value of copper Ni extent, wherea...
متن کاملTEMPLATE SYNTHESIS, CHARACTERIZATION OF HIGHLY UNSYMMETRICAL TETRADENTATE SCHIFF BASE COMPLEXES OF NICKEL (II) AND COPPER (II)
Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...
