摘　　要：采用溶胶-凝胶方法在S i(111)衬底上制备了ZnO∶Co氧化锌薄膜,利用X射线衍射(XRD)仪和振动样品磁强计(VSM)分别测试了样品的结构和磁性.实验表明,采用溶胶-凝胶方法制备的掺Co2+氧化锌薄膜具有(002)峰的择优取向,同时ZnO∶Co薄膜在室温情况下呈现出铁磁性.ZnO： Co thin films are prepared on Si （111 ） substrates by Sol -Gel Method. The structure and ferromagnetic properties of The samples can be investigated by XRD and M -H curve. The experiment suggests that The doped Co^2＋ ZnO thin film prepared by Sol - Gel Method has the preferred orientation on （002） peak. Besides that, ZnO： Co thin films owns ferromagnetism at room temperature.
