Determining the Anisotropic Exchange Coupling of CrO_2 via First-Principles Density Functional Theory Calculations
H. Sims, S. J. Oset, W. H. Butler +2
We report a study of the anisotropic exchange interactions in bulk CrO_2 calculated from first principles within density functional theory. We determine the exchange coupling energ…

Surface segregation in nanoparticles from first principles
Roman V. Chepulskii, W. H. Butler, A. van de Walle +1
FePt nanoparticles are known to exhibit reduced L1 order with decreasing particle size. The reduction in order reduces the magnetic anisotropy and the thermal stability of the…
