ELECTRICAL CONDUCTIVITY AND STRUCTURAL INVESTIGATION OF THE SYSTEM Zn1−xCuxMnxFe2−xO4

X-ray, electrical conductivity and infrared absorption studies for the system Zn1−xCuxMnxFe2−xO4 have been carried out. All the compounds in the range 0≤x≤1 show cubic symmetry. It is found that all the compounds of the system possess low mobility values in the order of 10−9cm2/Vsec and conduction is due to hopping process. The electrical conductivity measurements show that the activation energy decreases with increasing concentration of Cu2+ and Mn3+ in the crystal lattice. X-ray intensity calculations and IR studies indicated the presence of Zn2+ at tetrahedral sites, Cu2+ and Mn3+ at octahedral sites, and Fe3+ distributed both tetrahedral and octahedral sites. The probable ionic configuration for the system is suggested as
