The Influences of CuOZnO Ratios on the Crystallization Characteristics Electrical and Magnetic Properties of CuxZn1−xO Powders

الملخص EN

This study synthesizes CuxZn1−xO powders using an aqueous solution method.

The CuxZn1−xO 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 C0.5Z0.5O (1.5×105 Ω/□) powder was lower than that of CuO (5.82×105 Ω/□) powder after ZnO mixing in CuO.

This reduction was attributed to the substitution of Cu+ ions at Zn2+ sites or the formation of electron trapping defect centers.

The concentration ratio of Cu2O phase in CuxZn1−xO powder mainly dominated the electrical resistance.

The CuxZn1−xO has a diluted ferromagnetism (DFM) and paramagnetism (PM).

The electrical resistance of CuxZn1−xO decreased; the magnetic behavior increased instead.

This study also analyzes the chemical binding of Cu0.5Zn0.5O powders to confirm the contribution of Cu+ ions to the electrical and magnetic properties.
