English Abstract

The mixed polycrystalline Ni?????2−??4 ferrites, where x is the percentage increments of Al content, were prepared using the standard double sintering by mixing pure metal oxides ??2?3, Ni? and ??2?3.

The magnetization (M) was studied at room temperature as a function of applied magnetic field (H) over the range of (0-40) Oe in a constant magnetizing frequency (f = 50 Hz) and applied AC current (IAC) over the range of (0 – 5) A.

M showed increasing with increasing of H.

M found to decrease while the concentration of Al increases in matrix.

The decreasing of the magnetization with increasing of Al3+ ions is explained by Neel’s two-sublattice model.

The relation between H and relative permeability (μr) of Al – Ni ferrite samples shows that μr decrease for all samples as Al content increase.

Substitution of the non-magnetic Al3+ ions in Ni spinel ferrite has a tremendous influence such the magnetic properties.

So, the mixed Al – Ni spinel ferrite is considered a soft ferrite material, which is proved to be an interesting material for scientific and technological applications
