Nanoferrite, which has the chemical structure (Ni0.3Co0.2Zn0.5AlxFe2-xO4), have been produced with the use of the sol-gel auto–combustion approach that have (X=0, 0.1, 0.2, 0.3, 0.4 and 0.5) values. Samples are calcined at a temperature of (1,250oC) for a duration of (2 h), structure characteristics of the ferrite was confirmed by XRD. The results of the XRD have shown that the ferrite that has a size of the grain that ranges between (22 nm and 40 nm) and have a spinal Cubic phase, the x-ray result density (ρx-ray) has been decreased with the content of Al+3 . Electrical properties have shown that the dielectric loss factor and dielectric constant are reduced with an increase in frequency. Conductivity increases as well (σa.c) with the increase in the frequency value.
