Defect and adsorbate induced ferromagnetic spin-order in magnesium oxide nanocrystallites
(AIP Publishing, 2012-05-01)
We report the correlation between d(0) ferromagnetism, photoluminescence (PL), and adsorbed hydrogen (H-) species in magnesium oxide (MgO) nanocrystallites. Our study suggests that the oxygen vacancies, namely singly ionized ...
