We inserted CoO layer in NiO spin-valves to improve on magnetoresistance and exchange coupling field. The magnetoresistance ratio was increased from 4.5 % to 5.5 % with the increase of CoO thickness. We can not find the dependence between (111) texture and exchange coupling by the measurement of XRD of CoO/NiO spin-valves. The surface roughness of CoO layer, 6.1 Å is twice more than that of NiO layer, 3.1 Å. The increase of exchange coupling field and coercive field in the CoO/NiO spin-valves will be due to increasing roughness. We prepared the NiO/CoO/NiO/CoO/NiO spin-valves to reduce coercive field and the coercive field decreased from 110 Oe to 50 Oe, and the coupling field is not changed from 70 Oe.
