First-principles investigations of the orbital magnetic moments in CrO2
The electronic and magnetic properties of the ferromagnetic half-metal CrO2 have been studied by using the full-potential linear muffin-tin orbital method within the local-spin-density approximation ~LSDA! and the LSDA1U approach. The orbital magnetic moments are investigated by including the spin-orbit coupling in both schemes. Compared with the orbital contributions to magnetization in other ...
متن کاملFirst principles local pseudopotential for silver: towards orbital-free density-functional theory for transition metals.
Orbital-free density-functional theory (OF-DFT) with modern kinetic-energy density functionals (KEDFs) is a linear scaling technique that accurately describes nearly-free-electron-like (main group) metals. In an attempt towards extending OF-DFT to transition metals, here we consider whether OF-DFT can be used effectively to study Ag, a metal with a localized d shell. OF-DFT has two approximatio...
متن کاملFirst-principles determination of charge and orbital interactions in Fe3O4
The interactions between charge and orbitally ordered d electrons are important in many transition-metal oxides. We propose an effective energy model for such interactions, parameterized with density-functional theory plus U calculations, so that energy contributions of both electronic and lattice origin can be simultaneously accounted for. The model is applied to the low-temperature phase of m...
متن کاملOrbital magnetization in extended systems.
While the orbital magnetic dipole moment of any finite sample is well-defined, it becomes ill-defined in the thermodynamic limit as a result of the unboundedness of the position operator. Effects due to surface currents and to bulk magnetization are not easily disentangled. The corresponding electrical problem, where surface charges and bulk polarization appear as entangled, was solved about a ...
متن کاملOrbital magnetization in periodic insulators.
Working in the Wannier representation, we derive an expression for the orbital magnetization of a periodic insulator. The magnetization is shown to be comprised of two contributions, an obvious one associated with the internal circulation of bulklike Wannier functions in the interior, and an unexpected one arising from net currents carried by Wannier functions near the surface. Each contributio...
