Abstract

DC resistivity of Cu1-xZnxFe204 (x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) and Cu1-xSbxFe204 (x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5) are studied. Iron ion concentrations are also estimated to explain the observed variations in resistivity. Different types of conduction mechanisms have been noticed with these two substituents (Zn & Sb) having almost equal ionic radii..

Keywords

CuFe2O4, Resistivity, Blocking mechanism, Hopping mechanism.
