摘要

We investigated the room temperature ferromagnetism and their local coordination environment of Co and Mn doped in ZnO single crystal films. Both films show room temperature ferromagnetism and the saturated magnetization of the Mn-doped ZnO film is stronger than that of the Co-doped films. From the analysis on the local structures of Zn, Co, and Mn, we verify that the lattice distortions mainly surround the Co and Mn dopants. Due likely to the relatively large cation size, the Mn dopant would induce a greater local lattice distortion. We suggest that the local environment disorder between the Co and Mn dopants may play a role to the origin of ZnO based diluted magnetic semiconductor films.
