Structural and Magnetic Studies of Zn_(0.95)Co_(0.05)O and Zn_(0.90)Co_(0.05)Al_(0.05)O

         

摘要

Single-phase Zn_(0.95)Co_(0.05)O and Zn_(0.90)Co_(0.05)Al_(0.05)O samples were prepared by a novel combustion method.Xray diffraction studies exhibit the pure phase wurtzite structure of doped ZnO.Energy dispersive x-ray analysis confirms the incorporation of dopants into the host material.Scanning electron microscopy shows the ordered morphology in both of the samples.Temperature-dependent resistivity analysis describes the expected semiconducting behavior that is similar to the parent ZnO materials.Room-temperature magnetic measurements reveal the absence of ferromagnetism in Co-doped ZnO,while the Co and Al co-doped sample displays apparent room-temperature ferromagnetic behavior.The decrease of resistivity and presence of ferromagnetic behavior in Al-doped ZnCoO system corroborate the significant role of free carriers.
