The three typesof ferrites have been prepared by co-precipitation technique.
Theprepared ferrites were sintered at 800C?. while had emphasized the Crystallize
Synthesis accurately and Sort by these Synthesis by using the Technique (X.R.D).Then
using the these types of ferrite to prepared the final Synthesis( Ni Zn)xCd1-xFe2O4
with (X=0.7,0.4,0.2,0.0) to be eight samples halve of these as pressed pellets(12.3 mm
diameter, 5-4mmthickness)and later halveas triodes (Rin=9.85mm,Rout=19.4mm)All of
them were sintered at (1100 ?C) for (2 hr). the apparent density ,porosity were
calculated. The electrical characteristics for these samplesincluded the measure of A.C
current as The dielectric constant was calculated(?r ),loses factor(tan?) was measured
over same frequency range(20Hz-3MHz)to calculated the imaginary part of dielectric
constantand also the magnetic properties was measured by the same equipment, (initial
permeability ? ) was calculate after measuring the inductors(L),The VSM Technique
were used to study hysterics lope behavior of these samples.
