Phys.: Condens.

It is found that all of the geometry-optimized systems with the dopant atom replacing O in MgO exhibit half-metallic ferromagnetic properties regardless of metal or non-metal doping, and this agrees well with other theoretical computations. However, because of the high formation energy of metal atoms substituting for O atoms, we have calculated metal atom substitution for the Mg atom in MgO. We found that this system has a paramagnetic state and the formation energy is much lower than that of the former case. Finally, we have performed calculations for MgO doped with an F atom which shows a metallic behavior 9,文章納米盤鏈接:必須發(fā)到納米盤,方便進不了數(shù)據(jù)庫的朋友查閱。http://d.namipan.com/d/70378f7df ... 247a67172ffb3720b00 [ Last edited by dongdong3881 on 2010-11-17 at 17:06 ] |
