Structural, magnetic and dielectric properties of magnesium doped nickel ferrite nanoparticles

Magnesia doped nickel ferrite nanopowders (Ni1−xMgxFe2O4, x = 0, 0.1, 0.3, 0.5, 0.7) have been synthesized by co-precipitation method and all samples were annealed at 900 °C. The structural, morphological and magnetic properties of the products were characterized by X-ray diffraction (XRD), Fourier...
