Spin-Polarized Ground States and Ferromagnetic Order Induced by Low-Coordinated Surface Atoms and Defects in Nanoscale Magnesium Oxide
Takashi Uchino, Toshinobu Yoko
We investigate the effect of low-coordinated surface atoms on the defect-induced magnetism in MgO nanocrystallites using hybrid density functional theory calculations. It has been…

Symmetry and Nonstoichiometry as Possible Origin of Ferromagnetism in Nanoscale oxides
Takashi Uchino, Toshinobu Yoko
We show through density functional theory calculations that extended magnetic states can inherently occur in oxides as the size of the crystals is reduced down to the nanometer sca…
