A comprehensive review on recent advancements in d0 ferromagnetic oxide materials

d0 ferromagnetic oxide semiconductors have recently been proposed as a potential and alternative material with high Curie temperature ferromagnetism, which is important to realize spintronics devices operable at room temperature. We review the recent development in non-magnetic elements doped d0 ferromagnetic oxide semiconductors, including SnO2, TiO2, ZnO, ZrO2 and MgO. The experimental and theoretical results from recent literature on these atypical d0 ferromagnetic materials are discussed, with a particular focus on their magnetic properties.
