Abstract | We analyze the origin of ferromagnetism as a result of carrier mediation in diluted magnetic oxide semiconductors in the light of the experimental evidence reported in the literature. We propose that a combination of percolation of magnetic polarons at lower temperature and Ruderman–Kittel–Kasuya–Yosida ferromagnetism at higher temperature may be the reason for the very high critical temperatures measured (up to ∼700 K). |
