    The four types of ferrites have been prepared by co-precipitation technique<i>(Ni Zn Fe</i><i><sub>2</sub></i><i>O</i><i><sub>4</sub></i>,<i>Mg </i><i>Fe</i><i><sub>2</sub></i><i>O</i><i><sub>4</sub></i>,Mn<i> Fe</i><i><sub>2</sub></i><i>O</i><i><sub>4,</sub></i><i> Cd Fe</i><i><sub>2</sub></i><i>O</i><i><sub>4</sub></i>). The prepared ferrites were sintered at 800C ̊. Then using the these types of ferrite to prepared the final Synthesis Ni<sub>x</sub> Zn<sub>1-x-y</sub> M<sub>y</sub> Fe<sub>2</sub>O<sub>4</sub>wereM<sup>2+</sup>=(Mg,Mn,Cd)with (X=0.3),(Y=0.4) to be six samples halve of these as pressed pellets (12.3 mm diameter, 5-4mm thickness) and later halve as triodes (R<sub>in</sub>=9.85mm,R<sub>out</sub>=19.4mm). All of them were sintered at (1100 °C) for (2 hr). (XRD) Technique was used to study the structure of matrix Ni<sub>x</sub> Zn<sub>1-x-y</sub> M<sub>y</sub> Fe<sub>2</sub>O<sub>4</sub>, the apparent density , and porosity were calculated, The electrical characteristics for these samples included the measure of A.C current as the dielectric constant was calculated (έ ) ,loses factor (tan δ) was measured at the same frequency range (20Hz - 3MHz) to calculate the imaginary part of dielectric constant and also the magnetic properties was measured by the same equipment, (<i>initial permeability </i>μ ) was calculate after measuring the inductors (L), the VSM Technique was used to study hysterics lope behavior of these samples.<sub></sub>
