The system Cobalt substituted copperferritesampleswere synthesized by a conventional double sintering ceramic method.A series of doped Copper ferrites withcomposithion Cu 1-x Co x Fe 2 O 4 (x = 0.2, 0.4, and 0.6 ) are synthesized. The X-raydiffraction pattern at room temperature show that the sample exists in single phase with a spinel structure.Copper-Cobalt ferrites seriesaretakenand their electrical conductivityproperty are studied with a variation of composition and temperature. Log (σT) vs 10 3 /T is almost linear with a variation close to the temperature of Curie.In general, the paramagnetic region activation energy is greater than that of the ferromagnetic region’s.
