A series of nanocrystalline Li 0.25 Ni 0.5 Fe 2.25−x Er x O 4 (x=0.00, 0.02, 0.06, 0.08, and 0.10) ferrite powders, having a cubic spinel crystal structure and a low value of coercivity, was synthesized by the sol–gel auto-combustion route. The structure, morphology and magnetic properties of the prepared nanoferrites were characterized by powder X-ray diffraction...
Nano sized polycrystalline soft ferrite particles with composition Cu1−xCoxFe2O4 (x =0.1, 0.3, 0.5, 0.7, 0.9) were synthesized by the sol–gel technique. The existence of well-defined single cubic spinel structure was confirmed in all the samples by X-ray diffraction. The crystallite size found by XRD varied from 14.8 to 34.0nm. The microstructure was also characterized by scanning electron microscopy...
