Porosity and the Magnetic Properties of Aluminium Doped Nickel Ferrite

The nanocrystalline particles of Aluminium Al doped nickel Ni ferrites with general formula NiAlxFe2 xO4 x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were synthesized by sol gel auto combustion technique. The formation of single phase cubic spinel was confirmed by X ray diffraction analyses. Morphological features of the samples are studied by Scanning Electron Microscopy SEM to examine the particle size, shape and homogeneity of sample. The magnetic hysteresis graphs were obtained to understand their magnetic behaviours. The relative permeability µr of Al-Ni ferrite samples shows a decrease for all samples as Al content increases.
