First-principles prediction of enhanced magnetic anisotropy in FeCo alloys
Wu, Dangxin; Zhang, Qiming; Liu, J. Ping; Yuan, Dingwang; Wu, Ruqian (American Institute of PhysicsDepartment of Physics, The University of Texas at Arlington, 2008-02-04)The structural, electronic, and magnetic properties of FeCo alloys were studied by first-principles calculations. It has been found that the alloys prefer chemically noncubic geometries in a wide composition range. This ... -
A First-principles Study On Bulk CuO: Electronic Structures And Native Point Defects
Wu, Dangxin (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 ... -
First-principles Study On Hard/soft SmCo5/Co(Fe) Nanocomposite Magnetic Materials
Wu, Dangxin (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 ...
