Non-monotonic Fermi surface evolution and its correlation with stripe ordering in bilayer manganites
Z. Sun, Q. Wang, J. F. Douglas +11
In correlated electron systems such as cuprate superconductors and colossal magnetoresistive (CMR) oxides there is often a tendency for a nanoscale self-organization of electrons t…
Direct observation of localization in the minority-spin-band electrons of magnetite below the Verwey temperature
H. Kobayashi, T. Nagao, M. Itou +5
Two-dimensional spin-uncompensated momentum density distributions, s, were reconstructed in magnetite at 12K and 300K from several measured directional mag…
The Resonating-Valence-Bond Ground State of Li Nanoclusters
D. Nissenbaum, L. Spanu, C. Attaccalite +2
We have performed Diffusion Quantum Monte Carlo simulations of Li clusters showing that Resonating-Valence-Bond (RVB) pairing correlations between electrons provide a substantial c…
Extracting d-orbital occupancy from magnetic Compton scattering in bilayer manganites
B. Barbiellini, P. E. Mijnarends, S. Kaprzyk +4
We consider the shape of the magnetic Compton profile (MCP), , in LaSrMnO for momentum transfer along the [110] direction and the associ…
A spin-polarized scheme for obtaining quasi-particle energies within the density functional theory
B. Barbiellini, A. Bansil
We discuss an efficient scheme for obtaining spin-polarized quasi-particle excitation energies within the general framework of the density functional theory (DFT). Our approach is…
Magnetic momentum density, Fermi surface and directional magnetic Compton profiles in LaSrMnO and LaSrMnO
P. E. Mijnarends, S. Kaprzyk, B. Barbiellini +4
We have carried out first principles, all-electron computations of the magnetic momentum density and magnetic Compton profiles (MCPs) for momentum transfer a…
