This study synthesizes Cu x Zn 1 − x O powders using an aqueous solution method. The Cu x Zn 1 − x O powders with different content ratios of CuO and ZnO (CuO : ZnO = 1 : 2, 1 : 1, and 2 : 1) were formed. The crystalline characteristics and electrical and magnetic properties depended primarily on the mixing effect and oxygenation. The electrical resistance of C 0.5 Z 0.5 O ( 1.5 × 10 5 Ω / □ ) powder was lower than that of CuO ( 5.82 × 10 5 Ω / □ ) powder after ZnO mixing in CuO. This reduction was attributed to the substitution of Cu + ions at Zn 2+ sites or the formation of electron trapping defect centers. The concentration ratio of Cu 2 O phase in Cu x Zn 1 − x O powder mainly dominated the electrical resistance. The Cu x Zn 1 − x O has a diluted ferromagnetism (DFM) and paramagnetism (PM). The electrical resistance of Cu x Zn 1 − x O decreased; the magnetic behavior increased instead. This study also analyzes the chemical binding of Cu 0.5 Zn 0.5 O powders to confirm the contribution of Cu + ions to the electrical and magnetic properties.
