Effect of M²⁺ Substitution on Properties of the System Ni_x Zn_1-x_-y M_y Fe₂O₄

Full Text PDF

Abstract:

The four types of ferrites have been prepared by co-precipitation technique(Ni Zn Fe₂O₄,Mg Fe₂O₄,Mn Fe₂O_4, Cd Fe₂O₄). The prepared ferrites were sintered at 800C ̊. Then using the these types of ferrite to prepared the final Synthesis Ni_x Zn_1-x-y M_y Fe₂O₄wereM²⁺=(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_in=9.85mm,R_out=19.4mm). All of them were sintered at (1100 °C) for (2 hr). (XRD) Technique was used to study the structure of matrix Ni_x Zn_1-x-y M_y Fe₂O₄, 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, (initial permeability μ ) was calculate after measuring the inductors (L), the VSM Technique was used to study hysterics lope behavior of these samples.
