摘要：

Due to the large spin moment exhibited by the transition metal Mn, it is being extensively investigated as a candidate element for producing ferromagnetic ZnO for magnetoelectronic and spintronic applications. However, ferromagnetism in ZnMnO is being controversially discussed. We review our investigations on epitaxially grown ZnMnO layers and present findings on Mn-implanted ZnO layers. The results of our investigations on the magnetic properties of the fabricated ZnMnO show that it is not trivial to confirm ferromagnetism in ZnMnO grown on sapphire because of ferromagnetic signal produced by the substrate. After a deduction of the substrate contribution to magnetisation data, both epitaxially doped ZnO layers and Mn-implanted bulk and epitaxial layers show paramagnetic behaviour.
