Investigation of dielectric, electrical and optical properties of copper substituted Mn-Zn nanoferrites

Transition metal such as Copper substituted Mn-Zn magnetic nano ferrite with general formula Mn0.5Zn0.5CuxFe2-xO4 (x = 0.0, 0.1, 0.2, and 0.3) were fabricated by solution combustion method and expose how significant properties of the samples are modified accordingly by dopant concentration. By FTIR spectroscopy various functional group present in Mn-Zn ferrites is studied. The optical plots revealed bandgap energy reduced from 2.42 to 1.82 eV although the electrical study shown the highest conductivity of synthesized nano ferrite is 1.93 x 10(-8)Scm(-1). The dielectric constant as well as dielectric loss behavior recorded at room temperature and were analyzed with increasing temperature; both dielectric constant and loss tangent upsurge however with increasing frequency both are observed to reduce. Doping with Cu has the potentiality of accumulative dielectric constant and conductivity of Mn0.5Zn0.5CuxFe2-xO4 thereby improving its application for electromagnetic devices.

Automated summary

Copper-substituted Mn-Zn magnetic nano ferrites were successfully fabricated using a solution combustion method, and the effects of dopant concentration on the properties of the samples were studied. The research showed that doping with Cu led to a reduction in bandgap energy, an increase in conductivity, and improvement in its application for electromagnetic devices.
