he separation techniques are uniquely physical in nature
and operate without the usage of heat and thus utilizing
least energy as compared to the orthodox thermal separation
methods. In this research work we have analyzed the role
of substitution of Ce on the electric behavior and structure
properties of Cadmium doped Mn Zn ferrites. Series of

(x=0.0, 0.1, 0.2, 0.3, 0.4, 0.7) was
synthesized by coprecipitation technique. The synthesized
particles were sintered at 900
0
C. XRD analysis showed that
particles have cubic spinel structure. Crystallite size lied in the
range 46.4 nm-53.5 nm calculated by the Scherrer formula.
Crystallite size, lattice constant and x-ray density were found
directly affected by concentration of RE
3+
. By using two probe
method IV properties were studied at different temperatures.
It was observed that resistivity of synthesized nanoparticle
increases by increasing concentration of Ce and temperature.
The value of electrical resistivity lied in the range ~10
9
Ω
cm to ~10
10
Ω cm. Activation energy of these nanomaterials
lies in the range of 1.04 - 2.73. Activation energy decreases
with the increase in concentration of x. These characteristics
made these particles promising candidates for high frequency
applications.
