Abstract- The optical, structural and magnetic properties of Cr-doped ZnO disc-shaped pellet prepared by chemical precipitation method and thin films prepared by sol-gel method have been investigated. The XRD patterns for both samples show ZnO Wurtzite structure, no peak for secondary phase such as Cr clusters or chromium oxides is detectable within the precision of XRD which confirms that Cr ions enter the structure as dopant. All thin films show high transmittance in the visible region . And magnetic measurement carried out by magneto-optical Kerr effect (MOKE) confirms the ferromagnetic behavior of the pellet form sample.
Keywords: chemical precipitation, dilute magnetic semiconductor, band gap, magneto-optical Kerr effect, sol-gel.
