嵌入在基质中的磁性离子的分布的调制对于稀磁半导体的功能是至关重要的。通过特定元素的结构表征，我们观察到的形成和增强的一个未透露的Co掺杂的ZnO相，因此从顺磁性到铁磁性的磁性控制的表面改性。
The modulation of the distribution of magnetic ions embedded in the host is crucial for the functionality of dilute magnetic semiconductors. Through an element-specific structural characterization, we observe the formation and enhancement of an unrevealed Co-doped ZnO phase and consequently magnetic properties from paramagnetism to ferromagnetism are controlled by surface-modification.
