Abstract

The origin of ferromagnetism in a metastable phase rather than by carrier-induced interaction between separated Mn atoms in ZnO in a low-temperature-processed MnO₂-ZnO system was demonstrated. It was observed that the ferromagnetism persists up to ∼980 K. It was shown that a uniform solution of Mn in ZnO does not form under low-temperature processing. The direct low-temperature film growth of Zn-incorporated Mn oxide shows ferromagnetism at low Zn concentration for an optimum oxygen growth pressure.
