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.

It depicts the rapid increase of the absorption at wavelengths 340 nm. It indicated an Lithium index (Li2x) in the absorbance value, as the absorbance value increases with the increase of Lithium index (Li2x)
Summary
In the field of material science, Ferrites are well-known magnetic nanomaterial’s intensively studied as a recording media due to their superior physical properties [5] [6] [7]. These properties make ferrites an ideal candidate for technical applications such as magnetic resonance imaging enhancement, catalysis, sensors and pigments [8]. Spinel nano ferrites (AB2O4) are materials of today’s research due to their amazing structural, dielectric, electrical and magnetic properties [9]. Ultraviolet-visible spectrometer (UV) was used to study the optical, electric and magnetic properties of nanoparticles [16]
