Effect of M 2+ substitution on properties of the system Ni x Zn 1-x

ABSTRACT. The four types of ferrites have been prepared by co-precipitation technique(Ni 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 Fe 2 O 4 , 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
