Structural, optical, electric and dielectric characterization of a NaCuFeMnO compound.

The compound NaCuFeMnO was synthesized using a solid-state method and it crystallized in a hexagonal system with a 3̄ space group in an O3-type phase. The optical properties were measured using UV-Vis absorption spectrometry to determine the absorption coefficient and the optical band gap . The optical band gap energy of this sample is 2.
