摘 要: | 在200~500℃的衬底温度范围内,用电子束蒸镀法在Si衬底上制备了沿[002]取向的Zn0.80Co0.15Mn0.05O薄膜。这些薄膜都具有室温铁磁性,薄膜磁性随衬底温度的增大,在400℃出现极大值。X射线分析则表明,除200℃制备的薄膜结晶和取向较差外,其它温度的薄膜都沿C轴高度取向,(002)面间距和衍射峰半高宽(FWHM)接近相等。讨论了衬底温度对薄膜晶体结构和磁性的影响。

Abstract: | Zn_(0.800Co_(0.150Mn_(0.050O thin films prepared by method of e-beam evaporation on Si substrate at 200~500℃for substrate temperatures(Ts) are characterized using x-ray diffraction method, which shows all these films orientating well along except the film prepared at 200℃ and having similar crystal parameters. All these films having ferromagnetism at room temperature are found.Saturated and renament magnetization of the film grown at 400℃ is larger than one at other temperatures.The effect of Ts on crystal structures and magnetization of the films are discussed. |
