ABSTRACT: In this study, nano ferrite materials were produced to replace costive
industrial materials [1]. Ferrite nanoparticles are
the interesting material due to their rich and unique physical and chemical
properties. They find applications in catalysis, bio-processing, medicine,
magnetic recording, adsorption, devices etc. Using co-participation method, five nano ferrite
samples Zn0.5Mg0.5-xLi2xFe2O4 (x = 0.00, 0.10, 0.20, 0.30 and 0.40) were prepared. The electrical and optical
properties of the Zn0.5Mg0.5-xLi2xFe2O4 samples were studied using the Ultraviolet-visible (UV-Vis) spectroscopy. The
results verified that the formation of the absorption coefficient of the five samples
of Zn0.5Mg0.5-xLi2xFe2O4 increased with the increase of Lithium (Li2x). The energy band gap
of the Zn0.5Mg0.5-xLi2xFe2O4 samples ranged from 3.28 to 3.12 eV [1]. The extinction coefficient
(K) for five samples of Zn0.5Li2xMg0.5-xFe2O4 increased with the increase of Lithium (Li2x) at 338 nm from 0.074 to 0.207. The high
magnitude of optical conductivity is (1.34 × 1012 sec-1)
and the maximum value of electrical conductivity is 42 (Ω.cm)-1. This may due to the
electrical and optical properties of lithium.
