采用射频磁控共溅射法在玻璃基片上制备了非晶态Cu掺杂ZnO薄膜（ZnO：Cu）。磁性测量表明，非晶ZnO：Cu薄膜在室温下具有铁磁性，其饱和磁化强度远高于多晶薄膜。X射线衍射结果表明，非晶态ZnO：Cu薄膜中没有Cu 2 O相，这可能是薄膜具有高磁矩的原因。另一方面，非晶ZnO：Cu薄膜的高饱和磁化强度也可以归因于Cu在非晶ZnO溶剂中的固溶度没有限制。X射线光电子能谱研究表明，Cu以Cu ~（2+）化学状态存在。
Amorphous copper-doped ZnO thin films (ZnO:Cu) prepared on glass substrates by the radio-frequency magnetron co-sputtering have been investigated. Magnetic measurements indicated that the amorphous ZnO:Cu thin films were ferromagnetic at room temperature and the saturation magnetization was much higher than that of the polycrystalline films. X-ray diffraction results showed there was no Cu2O phase in amorphous ZnO:Cu films, which might be the reason for the high magnetic moment of the films. On the other hand, the high saturation magnetization of the amorphous ZnO:Cu films could also attribute to that there was no limit of solid solubility of Cu in amorphous ZnO solvent. The X-ray photoelectron spectroscopy study of the amorphous ZnO:Cu thin films reveal that copper was in Cu2+chemical state.
