The CuFeCr0.5Ni0.5O4 (CFO) compound was synthesized using sol–gel reaction combustion technic. structural analysis showed that the obtained composites have a polycrystalline nature and cubic spinel structure ( $${\text{Fd}}\bar{3}m~$$ space group). Microstructural revealed formation of spherical elongated grains our sample. dielectric electrical transport properties were investigated in detail ...
