摘要: Magnetism without d-orbital electrons seems to be unrealistic; however, recent observations of magnetism in non-magnetic oxides, such as ZnO, HfO2, and MgO, have opened new avenues the field magnetism. exhibited by these oxides is known d° ferromagnetism, either completely filled or unfilled d-/f-orbitals. This believed occur due polarization induced p-orbitals. Magnetic arises vacancies, excitation trapped spin triplet state. The presence vacancies at surface subsurface also affects magnetic behavior oxides. In present review, origins magnesium oxide are discussed obtain understanding ferromagnetism.
