Add to ORKGA series of solid solutions of composition Co3-xNixO4 has been studied. For 0 ≤ x ≤ 1·1 the members crystallize in the cubic spinel structure Measurements of dc electrical conductivity and Seebeck coefficient show that there is a transition from semiconducting state to semi-metallic state around x=0·5-0·6. All compositions withx>0.5 are semimetallic and ferrimagnetic. The results have been rationalised on the basis of the cation distribution (Co2+)t [NixIIICo2-xIII]0O4 for the solid solutions which permits formation of σ*(eg) band through strong covalent interaction between octahedral-site low spin CoIII/NiIII and oxide ion in the spinel structure
