Summary
The aim of this study was to synthesis Cd-M spinel nano-ferrites with
the general formula Cd1-x MxFe2O4 (in which M=Mn, Co, and Ni and x= 0,
0.25, 0.5, 0.75, 1) using a sol-gel combustion technique. The objective is to
improve the structural, electrical, and magnetic characteristics of prepared
(Cd-M)F2O4 spinel nano-ferrites by substituting M for Cd and to give a
complete structural investigation of spinel ferrite nanoparticles with more
precision characterization employing (XRD, SEM, EDX, and FTIR). In
addition, a broadband dielectric spectroscopy will employed to consider the
effect of Ni, Co and Mn–substitution on the electrical conductivity and the
dielectric behavior of the Cd- ferrite over a wide range of frequency and at
ambient temperature
