摘要: In a rather contradictory situation regarding magnetic data on Co-doped ZnO, we have succeeded in fabricating high-quality single crystalline Zn(1-x)Co(x)O (x=0.003-0.07) thin films. This gives us the possibility, for first time, to examine intrinsic properties of ZnO:Co at quantitative level and therefore address several unsolved problems, major one being nature Co-Co interaction ZnO structure.
