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), $J_{ma g} (p_{z})$ , in La $_{1.2}$ Sr $_{1.8}$ Mn $_{2}$ O $_{7}$ for momentum transfer $p_{z}$ 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 LaSr $_{2}$ Mn $_{2}$ O $_{7}$ and La $_{1.2}$ Sr $_{1.8}$ Mn $_{2}$ O $_{7}$

P. E. Mijnarends, S. Kaprzyk, B. Barbiellini +4

We have carried out first principles, all-electron computations of the magnetic momentum density $ρ_{ma g} (p)$ and magnetic Compton profiles (MCPs) for momentum transfer a…
