First-principles Study On Hard/soft SmCo5/Co(Fe) Nanocomposite Magnetic Materials
(Physics, 2008-09-17)
More than a decade ago, exchange-spring permanent magnets containing soft and hard magnetic phases have been proposed to enlarge maximum energy product values through exchange coupling between the magnetically soft and ...
A First-principles Study On Bulk CuO: Electronic Structures And Native Point Defects
(Physics, 2007-08-23)
In this thesis, we have performed a first-principles study on strongly correlated monoclinic cupric oxide (CuO) by using the LSDA+U method implemented in the PAW method. Based on the optimized structural parameters, which ...
