Abstract

Chemical method was employed to synthesize Mn and Al codoped ZnO, namely, Zn0.995-x Mn0.005 Alx O with the nominal composition of x=0, 0.005, and 0.02. Structural, optical, and magnetic properties of the produced samples were studied. The results indicated that introduce Al as additional dopants induces in an enhancement of the ferromagnetism in Zn0.995 Mn0.005 O. The enhanced ferromagnetism (FM) in (Mn,Al) codoped sample can be understood in view of that introducing of Al could promote spinodal decomposition and lead to Mn rich regions. The Mn rich regions could be responsibility for the observed enhancement of FM at room temperature.
