Evidence for room temperature ferromagnetism in CuxZn1−xO from magnetic studies in CuxZn1−xO∕CuO composite

Magnetic studies in bulk 57% CuxZn1−xO∕43% CuO composite prepared chemically with x=0.10 (0.03) are reported. Temperature dependence of the magnetic susceptibility shows clear signature of the Néel temperature TN≃230K for pure CuO. Hysteresis loop studies in the zero-field-cooled sample show room-te...

Zusammenfassung:Magnetic studies in bulk 57% CuxZn1−xO∕43% CuO composite prepared chemically with x=0.10 (0.03) are reported. Temperature dependence of the magnetic susceptibility shows clear signature of the Néel temperature TN≃230K for pure CuO. Hysteresis loop studies in the zero-field-cooled sample show room-temperature ferromagnetism with coercivity Hc≃50Oe at 300K with strong temperature dependence for T
